API Charts are no code dynamically generated graphs and charts where the data and parameters are input via the URL or in the Request Body. Most any feature can be modified such as colors, sizes, data sets, etc.
API graphs can be used as part of an automated workflow to generate an image to insert into an email based on current data without the need for temporary or permanent file storage. They also run as a microservice instead of a full blown web site. They were created using the Skia 2D Graphics Library.
