The Connecticut State Data Center has recently been working on visualizations that highlight some of the data available on the Connecticut Open Data Portal.
This fifth visualization takes a look at incidents reported to the Hartford Fire Department between January 1st and November 19th. There are four views; three are maps, and the other is an area chart that shows incidents over time broken down by zip code. Note that not all of these incidents necessarily involve a fire. When clicking on a point in the map, there is a link to a PDF with explanation of all the incident codes. You can see all of the original data here.
Just like other visualizations, this story also includes a GoogleMaps interface so you can look at incident locations using a satellite basemap or Google Street View.
