@Ted Clayton Breaking News!

There was an update waiting this morning for WP Chart Generator. It is now in English!.

I have to return to outdoor work, but later today will make another try on the 10-nation gun-statistics pie chart, and will try to link a screenshot of it here in the comments.

The author, Emilien laborde, has also update the official WP Chart Generator page on the WordPress plugin repository, to show it compatible up to the current WP_v3.5.2 ... and I think with a new screenshot.
