[![Build Status](https://travis-ci.org/rveciana/d3-marching-squares.svg?branch=master)](https://travis-ci.org/rveciana/d3-marching-squares)

Marching squares isobands and isolines ready for using along with d3 maps.

The marching squares algorithm code is taken from the [MarchingSquares.js](https://github.com/RaumZeit/MarchingSquares.js) project by [Ronny Lorenz](https://github.com/RaumZeit), adapted to work with nodejs.
