I wonder there are any tools or online tools which one can construct tree just giving datas. ex ; after giving datas, I want get a picture like ; google picture
Look into Graphviz, and its descriptive language DOT.
If you want an online/web style tool, you can try using the organizational chart graph from google charts which is very simple to use, though the 'square-ness' of the chart might annoy some, or you can try a more fancy flash API like Flare (the Demo contains various types of 'trees' under "layouts").

Scenario:
In Google Analytic, I notice that it is possible to replace certain URI parameter to words that you want by using search and replace filter like the following example below.
e.g. www.example.com/abc/product_id=3 -----> www.example.com/abc/product_name=shampoo
Problems:
Currently I've got a list of over 1000 products in my hand, instead of creating 1000 search and replace filter, what would be the most efficient and maintainable way to go solve the problem?
I've done some digging and notice that custom dimension could be the solution, however it would require me to modify the the JS code on the FTP sever which I dont have permission on. What other solutions do I have?
If it is not possible to show it here would there be any kind of tutorial that I could follow through?
Really appreciate for the help, Many Thanks
This is not a complete answer, but it's certainly more than a comment.
Besides the tedium of writing this out by hand, I can think of two options available to you.
Firstly, you could use the Google Analytics Management API (https://developers.google.com/analytics/devguides/config/mgmt/v3/). By constructing a set of commands, you could quickly iterate through your list and create the required 1,000 search and replace filters.
Secondly, if you were to use Google Tag Manager you would be able to create a Custom JavaScript Variable that takes the page path and compares it to your list. This variable could then replace the Page field before the hit data is sent to Google Analytics. This may sound more complicated, but it would allow you to pull your solution out of Google Analytics and into the flexible world of JavaScript.
Note that if you rewrite the product_id to a product_name once, you will have to maintain that cross reference every day and keep it in sync with what appears on the website -- make sure you have an automated solution or it will quickly get out-of-sync and be more of a mess than before.
An alternative is to do the search-and-replace on the reporting side.
I know Analytics Edge or Analytics Canvas products could easily do this, or you could just download into Excel or Google Sheets and do a series of lookup formulae.
I am trying to make a few interactive graph visualisations in my Django web application using Python. I found Graphviz and was able to output a static graph (as a .png image) on my application using Pydot (Python interface to Graphviz's dot language).
However, I am looking to make my graphs more interactive, like being able to highlight nodes when passing my mouse over it, making the nodes click-able, dragging the nodes to a different location and zooming on the graph.
Is there a way I could do this in Graphviz? Or in general is there way to make an interactive graph for my Django application without having to use Flash? I don't want to use flash since I'm not that familiar with it and also since I want to visualise a fairly large dataset.
Try The Javascript Infovis Toolkit. It is all implemented in a browser canvas, so no Flash is needed, only a decent browser with support for the <canvas> tag. Graph visualization examples are here, here and here, other demos are here.
There is Canviz (source). However, nodes are not yet clickable (they were in an older version that used image maps. The code base has changed and now the rendering is happenning client side using javascript, which is why clickable links is not yet re enabled.
This is the best I found, however they are plenty of others.
mxGraph (Not free)
You can use D3.js for graph visualization (see here for examples of graph visualizations in D3js, and look at How to Make an Interactive Network Visualization).
For back-end (if it is necessary to have something more than just a json file to represent the graph - i.e. if it is large), then you can use a Python module for graphs, NetworkX.
Side note, here is my simple interactive graph visualization example:
You can do something like this very simply just with DOT and HTML.
Generate client-side maps and overlay them over your PNG images. (Insert the map code into the HTML page.)
dot test.dot -Tpng -o test.png -Tcmapx -o test.map
SVG exports are directly clickable.
It seems like an approach that fits what you are trying to do might be to use svg in the browser an/or javascript. I think most of the modern browsers support SVG and would allow you to do some pretty cool interactive graphs. The server could provide a json feed of the datapoints needed to render the graph. I don't know off hand the tools that are available, but I've seen some pretty cool graph demos constructed without flash through client-side approaches.
As an alternative, you could pre-render a bunch of graph images that the user would likely view and then just fetch those as the user interacts with the graph. This might work if the graphs don't change that frequently and if the number of alterations that the user would make is small, but you'd have to re-render every time the graph changes.
I've did what you are trying to do not too long ago. The context was visualizing a gnarly SalesForce schema.
First thing, graphviz is only good for plotting, not really for drawing. You can generate SVG, but I could not get it to work with I.E. after a considerable of (what turned out to be fruitless) effort.
I DID find this Java Applet ZGRViewer to suffice, and while applets feel a bit dated for my taste, it worked very well cross browser.
I basically hand coded a process invoking service that generated the dot files and ran them thought (dotty, is think?) - the visulazation applet reads the native dot file format.
I also came accross something that I thought about for a V2 (which never happened) - it is part of the AJAX control toolkit - Seadragon.
If you want to see the code in ASP.NET, I can post it.
I'm looking for python modules that can help with grepping C++ code. I have a large code base that I would like to do some analysis on. Ultimately I would like to come up with a graphical map of the software. There is lots of message passing going on amongst apps so I would like to be able to capture that information and present it visually. I have been looking around at some of the data visualization packages but have only stumbled on math and plotting related ones.
What are the best tools for this job, preferably in python?
Your best tool for the job is Graphviz. If you look at their gallery you'll find the sort of thing that you're interested in along with links to projects.
Under the language bindings section here there are a few python entries. Personally I don't use them as the dot language format is simple enough that you can build up fairly complex graphs from Python just using print statements.
You ca look at doxygen and see if it does (at least some part of) what you want. It generates call graph and class diagrams directly in html or xml format (I believe you need to have dot installed for fancy graphs).
A sort of follow up/related question to this.
I'm trying to get a grip on a large code base that has hundreds and hundreds of classes and a large inheritance hierarchy. I want to be able to see the "main veins" of the inheritance hierarchy at a glance - not all the "peripheral" classes that only do some very specific / specialized thing. Visual Studio's "View Class Diagram" makes something that looks like a train and its sprawled horizontally across the screen and isn't very organized. You can't grok it easily.
I've just tried doxygen and graphviz but the results are .. somewhat similar to Visual Studio. I'm getting sweet looking call graphs but again too much detail for what I'm trying to get.
I need a quick way to generate the inheritance hierarchy, in some kind of collapsible view.
Why not just do it manually, it is a great learning experience when starting to work with a large code base. I usually just look at what class inherits from what, and what class contain what instances, references or pointers to other classes. Have a piece of paper next to you and get drawing...
Instead of going into the full Class Designer tool, just use the "Class View" or the "Object Browser" in Visual Studio - they present fully collapsible class heirarchies.
A good UML tool should do the trick.
Here is a list of generic UMl tools: http://en.wikipedia.org/wiki/List_of_UML_tools
There are lots out there, all with varying feature sets. Try playing with a few to see if you get the output you desire. If they free ones fail you, you might have to shell out for a good commercial grade UML tool
You can try CppDepend, it doesn't create a class hierarchy like Doxygen does but it can show 'the big picture' for your project, it also shows some code metrics.
I've had most success with valgrind and kcachegrind to do this. You run valgrind against your debugging binary, perform whatever actions your interested in, then import the output into kcachegrind to see everything you'd ever want to know about who called what, how often, and when. Plus, because your doing it dynamically, it catches cases that static analysis likely wont.
I've also had some success using Enterprise Architect's reverse engineering features, although this doesn't end up nearly as nicely (but you get a workable UML model which is nice!).
And finally, a tool called "Understand". This is pretty good at static OO analysis, but I think quite pricey and not that widely used.
Try Source Insight it is possible to configure the depth of the generated graph in this tool.
See also C/C++ call-graph utility for Windows platform
Check out SourceNavigator, it's open source, works on a bunch of platforms and has a Hierarchy Browser, a Class Browser, a Cross-Reference Browser and more that will allow you navigate and understand the code.
I'm using it for some time now especially when I have new code to go through and understand.
For a reasonably priced commercial product, you may want to check out SolidSX from Vizlogix (www.vizlogix.com). (If you are outside of North America, go to SolidSource -- www.solidsourceit.com.)
It generates a radial diagram that can be collapsed and expanded. It also integrates with Visual Studio (both BSC and .NET).
What's your definition of 'main vein'? You either want a graph reducer or skeletizer (you could find or write one and apply it to what Doxygen and the rest produce) or, 'main vein' has something to do with the function of the code and, I don't think an automated tool can help you with that. Unless you can point out to it 'These are the important bits that do input and output, show me only elements that are one or two steps away from the paths between these'. Hum, sounds like a cool tool to write :)
... the inheritance hierarchy, in some kind of collapsible view.
again, a sweet idea for a tool!
Could some one point to articles / books on how to create good flow chart diagrams?
BoUML-it's free!
I've used this open source tool for the last 6 months at work to create UML diagrams:
bouml.free.fr/
I've used it on both a Macbook running OS X, as well as Ubuntu Linux on a desktop, both with success. It also does codegen (although I haven't used this feature myself). If you create a diagram from within BoUML, you can right click ->Tools->HTML etc,etc., and it and actually generate the diagram -- this will create a whole tree of html, css, etc., and include a .png file which you can later choose to import into a Word-like document.
If you're new to UML, and would like to explore that route, I suggest UML Distilled by Martin Fowler as a way to quickly ramp up. I still use this as a reference when I'm putting diagrams together and I forget some syntactical detail ;) The nice thing about UML is that most programmers will understand it. If you don't want to buy a book you can, of course, Google 'UML tutorial' and get a slew of free info.
Non-UML:
You can also use open office's draw application to do some simple flow charting. It has some nice non-uml shapes, so if you're not trying to be 'strict' in the sense of conforming to UML, and just want a simple flow chart, that may be a good choice.
