Turn your data into a visual masterpiece
Components in picasso.js
Components are the visual building blocks that make up the chart, by combining them in various forms virtually any chart can be created. A bar chart, for example, consists of a bar layer, a continuous and a discrete axis. Add a line layer and you have a combo chart. Want a line chart with four axes? - Not a problem.
picasso.js is extensible
picasso.js provides a plugin system that makes it easy to extend existing functionality - you can register and use custom components that play well with the existing ones, create a new theme, provide your own data parser or even register a custom renderer that outputs sketchy graphics. picasso.js uses D3.js for a lot of its functionality and strives to provide the D3 community with a way to repurpose and easily integrate their work into picasso.js....

Apart from basic interaction patterns, interactivity in the form of brushing and linking is provided out of the box - drag a range on a linear axis to highlight all values that fall within that range, our use the lasso tool to highlight a cluster of points. The brushed values can then programmatically be linked and highlighted in another chart instance.
By using relative units and a unique layout algorithm we can ensure the composed charts are responsive. The same configuration can be used for a full sized chart containing details, annotations etc., as for a sparkline version - components are automatically resized or removed if they don't fit.
The visual look of labels, lines, shapes, color palettes etc. can all be modified and a new theme created by just changing a few base variables that control the look and feel throughout, including plugins.
