IE10+ DOMTokenList fix
View domtokenlist.js
* IE 10 + supports ClassList, but the standards are vague. It is extremely
* convenient to add several classnames at once, FF and Chrome support that.

* Hooking up Watchify with Google's Web Starter Kit
* The primary use cases for Browserify/Watchify are:
* - Node.js-style `require`s on the client-side
* - Use of npm modules on the client-side
* - No more new <script> tags for each new script/module
* 1. npm install --save-dev vinyl-source-stream browserify watchify gulp-notify

Click and drag above to paint red hexagons. A black outline will appear around contiguous clusters of red hexagons. This outline is constructed using topojson.mesh, part of the TopoJSON client API. A filter is specified so that the mesh only contains boundaries that separate filled hexagons from empty hexagons.

The hexagon grid itself is represented as TopoJSON, but is constructed on-the-fly in the browser. Since TopoJSON requires quantized coordinates, the hexagon grid is represented as integers, with each hexagon of dimensions 3×2. Then a custom projection is used to transform these irregular integer hexagons to normal hexagons of the desired size.

You can’t perform that action at this time.
