The Connecticut State Data Center has been working on visualizations that highlight some of the data available on the Connecticut Open Data Portal.
The first is a look at home sales (above $2,000) in the State of Connecticut during the year 2011. The data covers 140 of the 169 towns in the State. For each individual sale, the data includes assessed home price, actual sale price, geographic coordinates, and the unique sale serial number. You can see the original data here.
In addition to the more statistical views on the first page of the visualization, the second page features the data on GoogleMaps. This allows for changing the basemap to satellite imagery and even using Google Street View to try and get a look at specific houses.
