Circular Bar Chart Mod for Spotfire®

The Circular Bar Chart Mod for Spotfire® is a custom visualization built using Vega specifications. This mod provides a unique way to visualize categorical data in a circular format, offering an alternative to traditional bar charts by arranging the bars in a radial layout.

About Vega

Vega is a visualization grammar and framework for creating expressive, interactive, and highly customizable visualizations. It provides a declarative format for describing visualizations in JSON, making it easy to create complex visualizations with a concise and intuitive syntax. In the context of the Circular Bar Chart Mod, Vega specifications are used to define the visual properties and behavior of the chart, ensuring a high level of customization and interactivity. By leveraging Vega, users can create visually compelling and informative charts that enhance data analysis and presentation in Spotfire.
