Chart Names for Client Side Rendering

Hey,

So all charts get generated with the "drawChart()" function, which I bind the initial chart to the dom and render a new one. Any time a new chart gets rendered, all charts are redrawn. Also, if I need to update a chart, all charts are redrawn.

Any chance we can get an option to name the drawChart function for each chart? Defaulting to drawChart() is great, but an option would be nice.

Start by locating the drawChart() implementation and the code that binds charts to the DOM. Trace how new charts and updates trigger redraws, then determine where a per-chart naming option belongs while preserving drawChart() as the default. Done means each chart can use its own name without breaking existing rendering behavior; the payload names no tests.
