The columns are squished together so the titles are basically one word and the data creates a ton of empty space. The colors should be lighter shades. White on yellow is just annoying. The row separators don't extend to the row header, so it is easy to get lost when trying to compare the actual data.
As in the actual data is bad, inaccurate, opinionated and doesn't explain anything. Half of the chart is just "Cloudflare lol", like at least explain why.
It's a chart that looks useful at first glance, but the more you look at it the less you learn.
