AmCharts and amMap are customizable and attractive Flash graphics for your websites. Charts and maps can be used to illustrate simple financial trends or to show complex dated interactive data at irregular intervals. The tool can extract or read various data formats: CSV, XML, PHP, .NET, Java, Ruby on Rails, Perl, ColdFusion. The service is free, with a small company link (AmCharts, amMap) displayed in the upper left corner of the finished chart or map. To remove this link, a paid pro account is required. Click on images below to go to the site for more information and to get start.

A good example of very informative and rich with data interactive map by the New York Times. Checkout the timeline bar on top. The option to view data by foreign-born group on the upper left of the map is a plus. Click on screenshot below for large view. For interactive map, go to NYT

What I like about this map is that you can read the prices with color codes in state and county level, as well as zooming to street level for latest updates on prices at the pumps. I monitored several stations near my home and the prices were accurate or very close (like 1 to 3 cents off.) The options to select types of gasoline (in street level) is a plus. Enter a location name or a Zip Code for a try!
