Party like it's 1999
The Tableau Public blog focused recently on a map of Tea Party membership created by IREHR. Find the original post here.
Naturally when I see a map like this the first thing I do is zoom into my area. However, the IREHR visualization makes it difficult to do so quickly. The city and state data are already available, so I put it to use.
- The map is slow to load and update. I suspect this is due to number of points the map is drawing.
- The IREHR viz did not include Alaska, Hawaii and Guam, while it did included lots of members that did not have a location listed. I have filtered out the unknown locations and grouped the rest of the data more logically.
I made the following changes/improvements in my visualization:
- Added filtering by Region, State or City to allow you to quickly zoom into an area of interest
- Removed the size legend and replaced it with a caption on the map
- Add a link to the data source instead of just listing it
- Changed the membership numbers you see when you hover over a point to a whole number
- Changed the Faction filter to a slider instead of a single select option (saves space)
- Washed out the Faction color legend so that it's easier to see overlapping points
Which visualization is easier for you to use? I think it is easier and quicker to find what you need in my viz, but then again, I'm biased.
