This animated demo of Chiasm, a visualization runtime engine, cycles through configurations that combine a bar chart and a line chart in a split view, alongside a live configuration editor. The interactive editor lets you modify chart properties—such as data bindings, axes, colors, and titles—and see the updates render instantly. Built with reusable D3-based plugins, the example demonstrates how different chart types and data sources can be composed dynamically, with the bar chart plotting letter frequencies and the line chart showing temperature over time.
