Data Storytelling and Dataviz Approach
With this data, I wanted to look at the relationship between the income and expenses of the Post Office over time. However, due to quite a bit of inflation from 1790 to 2017, I had to calculate a ratio of expenses to income. Based on this calculation, I created a few calculated fields for use in my tooltip. I also created a donut chart (though I typically loathe them), for use as a viz in tooltip.
It's a pretty straightforward viz this week, with not too much commentary. What can you do with this dataset? Take some time to post your work to Tableau Public and Twitter with the hashtag #ThrowbackThursday, tagging @TThrowbackThurs. We'd really love to see what you can come up with!
This week's dataset comes from the U.S. Postal Service. Please be sure to cite the source on your viz.
