The bolded labels on the x an y axis show the which statistics from the 2014 census data are being displayed in the plot. Each light blue dot on the chart displays the aggregated value for a state. Hovering over a dot with the mouse will give the state name and exact values for the data point.
When a new xlabel or ylabel is selected, the data points will transition to their new locaitons in 1 second. The tick marks on the axis will also potentially move to better represent the new data set. Using the dynamic features of this plot, we can see 9 different plots but only use the space of 1!
