I need to create a Map to compare the population density of a country (e.g. USA at county -or state- level) and the epicenter of some earthquakes to see how many people could have felt those quakes.
The problem is that I can't find a way to put these 2 things on the same map.
In a db I have some earthquakes taken from USGS and the population data taken from Census.gov.
I was able to map earthquakes (coordinates lat/lng) with circles thanks to the Google Maps API but without population density.
I also created a map with Highcharts (Highmaps) to display population density, but I can't put circles on that because lat/lng points are not supported.
I also read about vectorWorkz and jVectorMap but couldn't find examples.
Is there a way to do such thing? I'm not an expert so if someone has a solution or could provide me a little example I would be eternally grateful. Thank you!
jVectorMap suits all your needs. Here is an example of regions density and markers visualisation on the same map.
