Radian is an open source JavaScript library that makes it easy to embed plots in HTML documents. It is being developed as part of OpenBrain’s BayesHive project. Instead of writing JavaScript plotting code yourself, you use custom HTML elements to represent plots. For instance, the HTML code on the left produces the plot on the right: <plot height=200 aspect=2 stroke-width=2 x="[[seq(0,4*PI,101)]]"
