I'm a linguist, not a geographer, and a first-time poster here.
I have some data about the use of a particular phrase in England between the years of 1225 and 1500. I have geolocations for the places where various manuscripts (MSs) were produced. I have the year (roughly) of the MSs, and I have token counts of the phrase in each MS. There are about 100 MSs, and thousands of tokens, but only tens of locations.
I want to produce a map with a slider that controls the year. I want a dot to appear in the MS location in the year when the MS is produced, and the size of the dot should grow as the number of tokens from that location accumulates over time.
So, if there was one MS in London in 1250 with 10 tokens, a small dot should appear at London when the slider is at 1250. As the slider is moved to 1275, the dot should remain stable. In 1300, a new MS is produced with 20 more tokens, so the area of the dot should now grow.
I've produced this in CartoDB, but it's not quite right. The number for the slider should show the year, not just an integer from 1-64, and I can't vary the sizes of the dots.
Is there something I can fix here or is there a better tool for doing this? I'm not married to any one platform, but as I said, I'm not a geographer, and I'm also not a web designer.
