Data Plot for the Variable of Percent Suicide by Gun

There is this concept of percent suicide by gun (PSG), which means the percent of suicides that are conducted by the gun. This measure is used as a proxy for gun ownership, because the more guns there are, the higher probability of using the gun to commit suicide. This data is obtained from the Center for Disease Control. Tracing the time trends for each state, we can see that for states that passed the law, the PSG measure of a large number of them increases, breaking the trend. The other states mostly see this measure decreasing over time.

Out of all 50 states, the ones that average the highest percent suicide by gun between 2000 and 2014 are listed below. Out of the top ten, only one state does not have the syg law.

Here is a gif with data between 1999 and 2014. Note that most of the states in the top are southern states, with the color of green.
