Blocks Graph III Voronoi Mouseover

this bl.ock is a step closer to using a Voronoi overlay for easier mouseover interactions with nodes. when you mouseover a Voronoi polygon, the polygon will appear, the circle representing the node that it contains will briefly grow.

      svg.selectAll("path.voronoi")
        .on('mouseover', function(d) {
          // highlight the node
          d3.selectAll("circle").filter(function (p) {
            return p.id === d.data.id
          })
            .transition()
            .duration(1200)
            .attr("r", 8)
            .transition()
            .duration(1200)
            .attr("r", 3)

          // show the Voronoi polygon
          d3.select(this)
            .transition()
            .delay(1200)
            .duration(1500)
            .style("fill-opacity", 0.4)
            .style("stroke-opacity", 1)
        });
