Crosslet is a free small (22k without dependencies) JavaScript widget for interactive visualisation and analysis of geostatistical datasets. You can also use it for visualizing and comparing multivariate datasets.

It is a combination of three very powerful JavaScript libraries:

  • Leaflet, an elegant and beautiful mapping solution, and
  • Crossfilter, a library for exploring large multivariate datasets in the browser.
  • D3, a data driven way of manipulating objects.

Crosslet also supports TopoJSON, a GeoJSON extension that allows to present geometry in a highly compact way.

Crosslet is written in CoffeeScript and uses less for styling.

Crosslet uses some latest web technologies including SVG, therefore it is not compatible with older browsers and browser which do not support SVG. Complex maps with more then a thousand items might cause Crosslet perform slower on non webkit based maps.
