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.

I have read through the Amcharts documentation, but I still can not figure out how to change the stroke width for each individual line. I did figure out how to change the width for all of the lines at the same time, but that is not what I want to do. I noticed when I made the lines thicker the map looked really messy, so this idea might not get off the ground even if I figure out the technical details. The issue is while I am pretty good at figuring out technical issues I do not have a strong foundation in using javascript libraries. I have an 11 hour YouTube video that I am planning on watching to build a stronger foundation, but I have not yet made the time to watch it. I keep on spending my time trying out new ideas on visualizing data. I have so many data visualizations I would like to build, I need more hours in the day to build them all. I hope I will get quicker with time

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.
