Following a few years old mathematics course I found that all the formulas coming from the retired Google charts were not working because of the discontinuation of the service.

For the graphic charts there are other drop-in replacements, but not for the text formulas, so I decided to create an online service that work as a drop-in replacement for it. If you have Google Charts text formulas urls you only need to replace the Google charts domain for the new service and the urls will be live again.

You can find many examples in it’s website: https://google-charts-formulas.vercel.app/

If you want to contribute to the code you can! If you found an error, please reach out!
