guys, I am working with the most recent beeswarm visualization by Mike Bostock.
I wonder, in D3js v.4, how to change the color of one single specific point. In this case, I am talking about unemployment in more than 180 countries, and I would like to single out only "Brazil" with a different color.
How can I pick Brazil's dot and make it with a different color? As last resort, I suppose I could use SVG to single it out, but its to big a code, burden. I am fairly new to D3.
Here is the code: http://codepen.io/voltdatalab/pen/KzrNGo
var cell = g.append("g")
.attr("class", "cells")
.selectAll("g").data(d3.voronoi()
.extent([[-margin.left, -margin.top], [width + margin.right, height + margin.top]])
.x(function(d) { return d.x; })
.y(function(d) { return d.y; })
.polygons(data)).enter().append("g");
cell.append("circle")
.attr("r", 5)
.attr("cx", function(d) { return d.data.x; })
.attr("cy", function(d) { return d.data.y; })
;
Here is what I want to do:
You need to add .attr("fill",function(d) { if(d.data.id === "Djibouti")return "red"; })
to circle. Following is the change you need to make:
cell.append("circle")
.attr("r", 5)
.attr("cx", function(d) { return d.data.x; })
.attr("cy", function(d) { return d.data.y; })
.attr("fill",function(d) { if(d.data.id === "Djibouti")return "red"; })
;
Replace Djibouti
with Brazil
. Here is a bin . Let me know if you want something like this.
