I was musing the other day about how my archives page would look much nicer if the category and date based archives were presented as heat maps. This sounded to me like a good idea for a plugin and I was all set to start coding when I thought I’d better check someone hadn’t thought of my revolutionary idea before! A quick google later and I came upon the “WordPress Heat Map plugin” which provides both heat maps for me. A few minutes later and it was integrated within the site and some CSS added to make it look pretty and all was done.
