Bump Chart

Before:  Up until last week, the kind of bump chart I knew was the one shown in Tableau Software’s on-demand tutorial .

It would look something like this one -- functional, basic, but a bit boring.

After:  Then I saw this souped up bump chart at the United States Census Bureau and was intrigued.  This chart not only shows the rank but also 2 additional metrics:  (1) change in population indicated by size and (2) change in rank indicated by color.  I thought that the use of color to indicate rank change is more meaningful than the use of color to display different languages.

Here’s the re-creation of that bump chart using Tableau:

Hope you like it.
