Ask HN: Google Image Charts alternative

Google Image Charts are deprecating anytime. I was searching for an alternative and could not find any that is comparable to Google's offering.

These static image charts helps in following use-cases:

* Embedding charts inside email. (no need to retain these on S3, etc) * Quick and lightweight sparklines using img tags. * Embedding charts inside PDF, etc is easier.

I started building an alternative to Google's offering which is compatible with Image Charts. Will you be interested in using this?
