Dear %username%,

I have recently come across several interesting and useful tools/libraries/events I would like to tell you about.

DC.js

This library allows creating great multi level/scalable cross-platform charts and diagrams providing instant feedback on user's interaction. A popular d3.js is in charge of the viewing process. crossfilter.js deals with the analysis of multi-dimensional data sets.

chart.renderlet(function(chart){
    // smooth the rendering through event throttling
    dc.events.trigger(function(){
        // focus some other chart to the range selected by user on this chart
        someOtherChart.focus(chart.filter());
    });
})
