Plottable.js is a library of chart components for creating flexible, custom charts for websites. It is built on top of D3.js and 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 a library of chart components. Check out examples of Plottable on our website's examples page.

Plottable's core philosophy is "Composition over Configuration", so a lot of the API flexibility is in choosing which Components to use, and how to arrange them in Tables, rather than setting high-level properties on the charts. If you find you need a feature that doesn't exist, consider writing a new Component that implements it as a plugin. This way, you can get your custom functionality and still benefit from the rest of the library. Drop a line at our Google group if you want help implementing a plugin.

Plottable.js is being developed by Palantir Technologies. It's developed in Typescript, and released in Javascript.

• Download plottable.zip or get it via Bower: bower install --save plottable
• Check out examples, read the docs and visit the website

If you just want to create a simple LineChart, ScatterPlot, or BarChart without worrying about Tables and Components, check out our sister library, Chartographer.js. It uses Plottable to create simple charts, and exposes all of the Plottable components so you can use it as a starting point and then add more complexity as desired.

If you run into any problems using Plottable, please let us know. We want Plottable to be easy-to-use, so if you are getting confused, it is our fault, not yours. Create an issue and we'll be happy to help you out.
