# d3 Chart Nodes Demo

# d3 Chart Nodes Demo

The [d3.js](https://d3js.org/) library allows for flexible and powerful visualizations of data in the context of HTML, SVG, and CSS. For this demo, we used _d3.js_ to create an [INodeStyle](https://docs.yworks.com/yfileshtml/#/api/INodeStyle) that displays dynamically changing data as a bar chart.
