Google maps has been displaying the primary results. Up until recently, the way they showed the results nationally was by coloring each state to show who won the popular vote there, yellow for Hillary, blue for Obama. When you selected a particular state, the data got a little more granular: It showed how each Congressional district had gone, again by coloring it yellow or blue.
Within the last few days, they changed it to provide more data visually. Instead of simply coloring the state one way or the other, each state is marked by a pointer of that color, and the size of the pointer is proportional to the number of votes cast in that state. When you click on the pointer, it gives you the date of the contest and actual vote totals for each candidate. And now when you click on an individual state, the vote results in every county are shown, again with a color-coded and size-adjusted marker.
For example, here's Texas (click to embiggen):
Pretty cool. Each of the markers is clickable, and it gives you the actual vote total for each candidate in each county.
