I really like Mark’s idea of standardised “sparkicons” …for a while there, reading this, I was worried he was going to propose something like Snap Preview. shudder
Remember when I made that canvas sparkline script? Remember when Stuart grant my wish for an SVG version? Well, now Tom has gone one further and created a hosted version on sparksvg.me
Not a fan of sparklines? Bars and circles are also available.
Microsoft are trying to patent sparklines. Twunts.
