This doesn't appear normalised making it pretty worthless. Meaning is car A sells 2x as many as car B, then car A will likely be "more likely to kill you" on this chart, regardless of how safe it actually is (even if it was much safer than car B).

It would be much more interesting to make a chart with an ordered ratio with [car] total sold/[car] death per million. At the moment all you're telling us is which cars sold a lot.
