Not a journalistic example yet, but I recently started editing a website of an academic reasearch about the education on a specific region of Brazil.
The project started long before I became part of it, and when I did, I noticed they used Tableau to show their data.
While we have some pretty good graffics, I'm suggesting changes in some of them. One is the following, that only shows the numbers and map, but not any bars:

I believe some of them aren't very clean too. But within some time we should be able to fix this.
