Data Visualization similar to Chartio?

Hello PHers! Back in the day my previous start-up adopted the amazing platform Chartio and found it super easy and quick to implement and utilize (also helped they were just around the corner so I was able to go bug them in person with my inane questions). I know they have now been acquired by Atlassian which seems like a pretty heavy duty system (could be wrong, but being prelaunch it looks intimidating!) I was wondering if anyone here has advice on or experience with a similar, lightweight service?
