Really Cool Stock Market Visualization
I was looking over some financial sites the other day and ran across this visualization that is based on the stock market. The overall presentation is divided into blocks of companies grouped by sector. The size of the company within their sector is based on their market capitalization, and the color indicates the current stock price trend. Clicking on a sector allows the viewer to “drill” down into the sector data. At the bottom of the frame is a drop-down that allows you to specify the time range used to identify the up or downward trend, with options for since last close, 26 weeks, 52 weeks, or year to date. While the color (green or red) shows the direction of the stock price move, the intensity of the color shows the percentage of the move. A company like Barrick Gold which has dropped substantially during 2013 (down ~48%) is fairly bright red, while PepsiCo (up ~25% YTD) is a muted green.
I think this is one of the best uses of this visualization style that I have seen, and decided to share it.
