After a first-time visit to the village in Lichuan, Hubei, Central China where my grandpa was born, I am back. I gained some new perspectives on the changes in the past hundred years.
The
Viz of the Day on 10/12/2016 is about the spells in Harry Potter books. I didn't know that spells could be this powerful such that the author Skylar Johnson is invoked to create this special viz. Very nice work! I see that even the labels match the colors of the data marks, which is a new feature in Tableau 10.
One thing I found possible to tweak is the histogram bar chart at the upper part of the viz. It shows the number of spells in each of the 7 volumes of Harry Potter. Under it, is the circle chart where we also see colored divisions by book. I feel that they should be aligned.
So here is the result of the tweaking. The data marks I used are lines whose sizes are proportional to the number of spells. The lengths of the lines also align with the page positions.
Click the above images to view and download the interactive versions. Below is an enlarged view of the histogram on spells per book. The axis are custom adjusted to align with the circle chart.
