On twitter I follow many charting and visualization related accounts. One of them is @Andy Kriebel, who runs Makeover Monday. The idea is simple. Every Monday they publish a data-set and ask the community to visualize. Last Monday (7th May, 2018), they have published about toughest sport by skill data. This categorizes 60 sports by 10 skill categories to find out which sport is the toughest. Over the weekend, Andy posted a summary of all toughest sport viz entries. Many of the entries are made in Tableau. I thought it would be a fun challenge to re-create some of these charts in Excel. The result is this post. 60 sports in 6 charts. Check out the charts and download workbook to learn more.
First four charts are re-creations of Tableau designs. Last two are mine.Continue »
