protovis | A visualization toolkit for JavaScript using SVG | Data Visualization library

Current libraries for making "interactive SVGs" in the web-browser are actually using javascript to manipulate a svg object in the page dynamically but don't actually embed the full javascript needed to animate the SVG in the svg tag itself. Libraries like d3.js, protovis, svg.js, etc.

But it's possible to create standalone interactive SVGs, for example Brendan Gregg's flamegraph tool, example: http://www.brendangregg.com/FlameGraphs/cpu-bash-flamegraph.svg

Is there any way to create a standalone, interactive SVG in a webpage? Of course, you could generate the interactive SVG serverside (for example, Brendan uses a Perl library to generate the interactive SVG) and then serve that to the user. But I'd prefer to generate the SVG as part of generating the webpage itself, i.e. in Php or Ruby or, even better, client-side with a Javascript library. In either case, the key feature goal is to be able to right-click-download the custom-made interactive SVG.

Note: The benefit of the d3.js approach is that the animation can be integrated between the SVG and other DOM elements on the page, or have interaction with the SVG trigger dynamic AJAX requests. I'm not expecting the stand-alone SVG to be able to do these things.

I would like to plot the result of certain analysis using a parallel coordinates chart. Having found a brilliant example made using protovis http://mbostock.github.io/protovis/ex/cars.html and I am trying to re-arrange my data to replicate the structure of the data file as per the example (cars.js). Hence, my dataframe structure:

Need help to generate the colors in chart

Problem : I am creating d3 chart - QQ plot, I want to add colors to each part of the chart. But I am not able to do it, so required help on this.

Thank you for your valuable time.

Any help is appreciated

Refrence. I am considering D3 QQ plot over protovis QQ plot due to ease of customisation.

Data will be binded in following code

I need to build a graphic train schedule visualisation tool in C#. Actually I have to rebuild this perfect tool in C#. Marey's Trains The graphs have to be zoomable, scrollable and printable/exportable to PDF with vector graphical elements.

Could you give me some tips? How should I start it? What sort of libraries should I use?

Is it worth to try using graphing libraries like OxyPlot? Maybe it's not the best because of the special axes and irregular grids - as I think. What's your opinion?
