Hi! We are trying to find new ways to play with data and make things more interesting and sortable. One thing we're working on is the best way to show artist, year and billboard chart ranking in different ways. Here is one chart-in-progress tracking year released, ranking on the Billboard Hot 100, and length on the charts corresponding to circle size.
Here is another chart that shows artist in relationship to time, rank and gender.
These two charts are similar at the moment, still looking for ways to refine them. We'll work that out today.
Other things to come: a sampling page, more ways to sort the original grid page and maybe even a playlist generator.
