In As Firearm Ownership Rises, Florida Gun Murders Increasing the reporter leads with a gun death story before using numbers which makes the dive into more numbers smooth.
The amount of gun murders is then released from 2011 and 2012 with a percent increase between the years included.
At the bottom of the story an interactive graphic that appears to be just a graph comparing the number of murders in Florida by firearms across the years brings up the the exact number of deaths. This is helpful because then the reader doesn't have to have estimated number by where the line marks with the numbers on the graph.
The reporter would have to know how to plot a spreadsheet and enter each record in the cells and then slice the pop-ups in a web editing program to provide the exact number of deaths when the mouse goes over the each part of the graph.
