Yep, HumblePie is not working with correct numbers.
There are 11,000 firearm homicides a year. (

There are 19,000 firearm suicides a year. (
http://www.cdc.gov/nchs/fastats/suicide.htm)
There are a total of 30k firearm deaths a year.
If you read the CDC they also have other categories like accidental discharge of firearm (606 deaths), undetermined intent use of firearm (252), legal intervention (412). So I'm quite sure they wouldn't wrap legal defense under the 11k homicide figure.
It's pretty hilarious how this thread got polluted by gun guys freaking out about an accurate and unbiased graph.
