This is a funnel plot and a map.  On the left hand side, there is a univariate choropleth map showing the proportion of the population which are in criminal institutions.  The classifications are divided by quantiles.  Each of the regions is a data point in the funnel plot.  The Number of People Institutionalized is on the x-axis, and the Percent of the Population Institutionalized is on the y-axis.  The Iberville Parish is highlighted by the yellow lines.  It has roughly 3,000 people in prison, which is 93% of the population.  The funnel plot is a tool to give more information to a choropleth map.
