The Gliffy PHP SDK by Gliffy allows API interaction, providing drawing features such as diagrams and flowcharts that developers can integrate into visualization applications. Resources include installation and configuration. To use the SDK, experiment creating a new diagram in PNG format.
In 2016 Google released Quick, Draw!, a digital version of Pictionary that uses machine learning to guess what users are drawing in their browser. Google is now providing the entire data set behind this algorithm as an open source API, allowing developers to research the way people draw.
Chart APIs are useful and popular, and Google knows how to do them well, so they're continuously adding more features and options for customization to their Visualization API. The Google Code Blog recently highlighted a few of the newest features.
Gliffy, a browser-based diagramming and flowchart tool, today announced the public availability of their new API (technical details at our Gliffy API Profile). The four year old company announced the new API on its blog, noting that Gliffy hopes to take advantage of the growing trend of companies that are unlocking their APIs to extend the reach of their applications and data.
