The visualization analyzes the connection between where meteorites have been found and who is interested in doing research on them.
After a long time of researching and prototyping the fact that caught me most about the meteorites was the contrast between where meteorites have been found and who is doing research on them.
My first approach to make a visualization about meteorites was to compare the monetary value of different meteorite classes. I discovered a lot of meteorite collections on the web, but I realized after some experimenting with the data, that too many collections are missing.
So I went back to the original data source (Meteoritical Bulletin Database) and discovered a nice detail. Most meteorites have a connection to an institute or private person who found or analyzed them. With this knowledge I created this visualization.
Meteorite Count Calculation
Due to the fact that most meteorites were found by severeal people working for different institutes I decided to count one found meteorite for every researcher involved. This results in a bigger total amount of analyzed or found meteorites than the actual amount, but point numbers could be avoided.
