 Fit one or more cubic Bezier curves to a polyline.
+JavaScript implementation of Philip J. Schneider's "Algorithm for Automatically Fitting Digitized Curves" from the book "Graphics Gems".
 
-This is a CS/JS implementation of Philip J. Schneider's C code. The original C code is available on http://graphicsgems.org/ as well as in https://github.com/erich666/GraphicsGems
+Ported from C via Python:
+* Original (C):
+  * https://github.com/erich666/GraphicsGems/blob/master/gems/FitCurves.c
+* Python:
+  * https://github.com/volkerp/fitCurves
+* CoffeeScript/JavaScript + math.js/lodash:
+  * https://github.com/soswow/fit-curves
 
-This implementation uses [mathjs](https://github.com/josdejong/mathjs)
+**No dependencies.**

+Usage
+-----
 
 ```javascript
 var fitCurve = require('fitCurve');
 var points = [[0, 0], [10, 10], [10, 0], [20, 0]];
-var error = 50; // The smaller the number - the much closer spline should be
+var error = 50;  //Lower numbers give more accurate curves.
 
 var bezierCurves = fitCurve(points, error);
 // bezierCurves[0] === [[0, 0], [20.27317402, 20.27317402], [-1.24665147, 0], [20, 0]]
 // where each element is [x, y] and elements are [first-point, control-point-1, control-point-2, second-point] 
 ```
 
-You can play around with that in this [demo](https://soswow.github.io/fit-curves/demo).
