With WordPress 4.7 we gained REST API endpoints for core data types—now what can we do with them? We’re seeing how the REST API is being used to build new and better editing interfaces, but we also have a huge opportunity to use that API to explore the data we already have within our sites. It’s never been so easy to access our WordPress content from JavaScript, so let’s see what we can learn about it through data visualization! I will share how we can combine the REST API with visualization tools like D3.js to gain new insights into your content. We will build a network diagram to visualize how tags and categories area applied to posts, then discover how to use custom post types and register_meta to build a completely custom dashboard within WordPress for any type of data.
