A tree map presents a considerable amount of data in a visual format to show you a lot of information at a glance. In this case you’re seeing all of the S&P/TSX Composite stocks in their respective industry sectors, from largest groups (upper-left) to smallest (lower-right). We’ve computed one-week forecasts for each stock, indicated by colour (bright orange, meaning highest likely gain) to dark blue (largest decline expected). The more orange the more up-trending stocks, the more blue, the more decliners. Left-click on the stocks for more info, and right-click to zoom in/out on a sector. The area of the stock rectangle represents consistency. You can reverse whether colour or size represents those two dimensions.  If you do, the stocks with negative trends will disappear, and you can concentrate on the winners.
