Shiboronoi

  wow
         such voronoi
                 html5
     many cells
                       very convexity
   so tessellation

var width = 960,

var voronoi = d3.geom.voronoi()

var canvas = d3.select("body").append("canvas")
    .attr("width", width)

  }

      context.stroke();
      context.restore();
    });
  }
});

  for (var i = 1, n = cell.length; i < n; ++i) context.lineTo(cell[i][0], cell[i][1]);
