Plottable.js is a library of chart components for creating flexible, custom charts for websites. It is built on top of D3.jsand provides higher-level pieces, like plots, gridlines, and axes. As such, it's easier to quickly build charts than with D3, and the charts are much more flexible than standard-template charts provided by charting libraries. You can think of Plottable as a "D3 for Charts" — it is not a charting library but rather a library of chart components. Check out examples of Plottable on our website's examples page.
