I modified one of the Amcharts demos called map with curved lines to make a Maryland map with lines. I want to show how students transfer among colleges at universities in the state using a map. I have successfully created the base map, but I have not yet figured out how to add a stroke width to the lines. I think it would be interesting to have the thickness of the line represent the number of students that transferred. I want to see if location is a factor in transferring.
Maryland Map with Lines
If I decided to go this route I just need to take the time to enter the names and longitudes and latitudes of all of the institutions. For this map I just googled the institution and “longitude and latitude”; however, I just discovered the U.S. Department of Education College ScoreCard data download has longitude and latitude information. In the future I will try using the ScoreCard longitude and latitude information.
