DC3 Design4: Treemap & Integrated vizualization of 'alsos'

WAIT! Embedded from https://jsfiddle.net/ Click on a block to expand and hover to get the product count in the subtree. SCROLL down for the multi-design integrated idea for visualizing the similar products (or 'alsos')

Integrated vizualization of 'alsos'.
'alsos' count value is color encoded i.e. continous hue saturation. Selecting "Books" and "Health & Personal Care" in tree map generates a popup window where we have the common items across the selected categories and bar chart shows the most frequent common items. The visualization is just for representational purpose
