TIL that Excel has this thing called “Sparklines” where you can have a mini-chart or visualization of your data in as small a space as a single cell. I made samples of the 3 types of Sparklines (Line, Column, and Win/Loss) captured in the image below. In each of the table, the last column displays the sparkline created for the data in the same row.
The Sparklines thingy is available from the Insert menu of the Excel Ribbon.
