Check out the 3 new Google Map Samples in Tour de Flex.
The Circle Creator, by Shigeru Nakagaki, lets the user create circles with various parameters (radius, color, etc.) on the map.
Andrew Trice created an XML Data Visualization sample that shows how to parse an XML file containing temperature data for U.S. cities and then create markers based on the data. Check out what else makes this a cool sample!
We also added a Zoom Slider sample by Pamela Fox that shows how to use an HSlider above the map to let a user control the zoom level of a map.
