We've published a new demo: [JSON Visualization](https://www.jointjs.com/demos/json-visualizer)

Today's demo shows [how to write a simple JSON visualizer using JointJS+](https://codepen.io/jointjs/pen/WNJBMxQ/2b00c86d873614abb88d8a47ae9bbdd8). Use TreeLayout to automatically position nodes and add Record shapes to organize object properties into tables where values have different styles depending on their type.

See the Pen [JointJS+: JSON Visualization](https://codepen.io/jointjs/pen/WNJBMxQ) by JointJS ([@jointjs](https://codepen.io/jointjs))
