I’ve tried to make some hexagon-based map in SVG. Unfortunately, there are white spaces between fields.
I’ve disabled fields’ borders (stroke=”none stroke-width=”0″), rounded all floating points to integers and made sure that hexagons have common points (no space between them). It didn’t help.
Two screenshots shows same SVG in different magnifications https://i.stack.imgur.com/Zta2b.png
Source code is here: http://pastebin.com/hqwTKW4M (remember to change extension to svg, after download).
Setting shape-rendering property to ‘crispEdges’ for all hexagons (or group of them) solves this issue. E.g.
