about_finviz

FINVIZ is a suite of free financial tools that takes advantage of modern visualization ideas.  The infoviz and interaction designs are certainly worth a blog post.  Here’s a look at their efforts…

1. Sector Visualization.  This visualization is a treemap implemented using the Google Maps API.   It shows how well sectors and companies (stocks) within those sectors are doing.  The attention to detail is exceptional.  The company name stays the same size on zoom, and is dual encoded using a background image.  The gain/loss is shown using shades of green/red, and is also dual encoded using text.  On mouseover details are provided in a side panel.

2. Stock Charts.  When you create a portfolio of stocks, a number of views of that portfolio.  One is a small multiples view which allows easy comparison without overlay as one has to do with Google Finance and Yahoo Finance charts.  Again, attention to detail is wonderful.  The current price is highlighted, the trendlines are nicely colored, and the volume barchart is part of the background.

 3. Trends.  They use Sparklines for trend indicators.  Well, they may just be icons (not encoded by actual data), but I’ll delude myself nonetheless.

4. News. They aggregate the news items for all the stocks in a portfolio onto one page.  Very nicely done.  Only shows the day, month, year, when they change.  Overlays chart when mouseover of price (notice the little icon to indicate this next to the word price…attention to detail).

5. Profiles.  Again, just very nicely done, showing all of the profiles on the same page.

6.  Relative Volume Indicator.  A second vertical axis is added.
