WebSep 12, 2012 · A distributive flow map made by Charles Joseph Minard showing coal exports from England in 1864. Unfortunately, there are no built-in tools in ArcGIS to generate distributive flow maps — the only way to make one with the software currently is to draw and attribute it by hand. So I wrote my own. How it Works.
