And they look really spidery too

Another great Excel article from Mynda Treacy​, this time about her​​ views on radar charts. It’s safe to say she’s not a fan. Some great points here about data visualisation and how to get messages across. I’ve never used a radar chart, but that’s more because I’ve never really understood them.

She mentions this article ​by Stephen Few, who weighs in further but does recognise when these radar charts might have their uses.
