install d3-renderer
Or
clone git@github.com:seantis/d3-renderer.git

install
Now you can run the service:
.
Or the PhantomJS version:
de_modules/.bin/phantomjs server.js
The node version is faster but does only support SVG generation at the moment and bounding boxes only to some extent.
Simply POST your code to http://127.0.0.1:1337 and arguments and receive the SVG, PNG or PDF in return.
The service expects code following a slightly modified version of Mike Bostocks reusable charts pattern. Define your code as follows.
myNewChart = function(params) {
var data = {};
// add more parameters such as width, height, ...
if (params) {
if (params.data) data = params.data;
// initalize the other parameter ...
}
var chart = function(container) {
var svg = d3.select(container).append('svg')
.attr('xmlns', "http://www.w3.org/2000/svg")
.attr('version', '1.1');
// more rendering ...
return chart;
};
// optionally add chained getter/setters ...
return chart;
The code can then be used locally as follows:
chart = barChart({option: value})(el);
or as follows:
chart = barChart(el);
elect(..).call(chart);
Send the script together with the parameters as JSON to http://127.0.0.1:1337/d3/svg, http://127.0.0.1:1337/d3/pdf (PhantomJS only) or http://127.0.0.1:1337/d3/pdf (PhantomJS only).
Add the scripts in order you want to run them (the latest d3js version is already set up, no need to include it).
"scripts": [
"/* content of d3 plugins (optionally) */",
"/* your code */",
],
"main": "myNewChart",
"params": {
"data": {}
}
Note that the PNG and PDF is returned Base64 encoded due to a nasty bug (https://github.com/ariya/phantomjs/issues/13026).
The PNG and PDF might need to know the size of the viewport, you can specify them by adding a viewport_width and viewport_height to the params. Alternatively, you can implement a getter width and/or height in your chart.
There are some solutions for PDF rendering of SVG images:
