Boilerplate starter code for Chiasm.
This example demonstrates the minimal code required to get started developing your own Chiasm applications and custom plugins.
The Chiasm plugins demonstrated here are:
chiasm-layout A Chiasm
plugin for nested box layout. You can use this plugin to impose a grid system
of rectangles on any collection of Chiasm components.
coloredRectangle An example custom Chiasm component that draws a colored
rectangle using D3.js and
SVG.
