These will quite possibly be the least exciting charts you'll see today, maybe even this week.
So why are they here?
Some of the work we do isn't sexy. It's not flashy, no sweet animations and doesn't have exciting new colour combinations.
Instead, it fits in with older (legacy) applications and just gets the point across. There's Arial. Simple flat shapes. No fancy effects. Heck, this could go straight into a PDF. Printed in black and white, and still work.
So why share it? Because it gets the job done. And that's worth as much as anything.
