Visualising Data with L2

Abstract

L2 is a new compile-to-JavaScript language for data wrangling, analysis and visualisation. The language is used in its own interactive environment (desktop or browser-based); compiled code will run in any browser or Node.js. To visualise data, L2 uses high-level libraries for simple plots, but also makes it easy to create SVG or canvas-based visualisations from scratch. Here, we discuss the various approaches to visualising data in L2 and consider a simple example.
