Synchronised Histograms with Menu-filter and Brush-filter

A bespoke histogram is combined with some dummy-data, a menu-filter (green button) and a brush-filter (top line-chart) to enable progressive filtering of the data by dimension. The circle-histograms allow control of the four dimensions, x, y, color and radius, allowing for a succinct presentation of data correlations. The x and y axes of the histograms are synchronised for demonstration.
