The earlier example of this brushable radial chart led to some feedback to make the filtering better. I introduced a #circularBrush.filter(array,accessor) that takes an array of data and and accessor for that data and returns to you the data that falls into the area of the brush. The functionality of this chart is no different than the other, but if you take a look at the code, it's much more efficient.
