V2 radar chart vis

The V2 Radar Chart Visualisation provides a custom D3-based radar chart visualization for Splunk. This visualization enables users to plot multivariate data on a two-dimensional chart across multiple axes, allowing comparison of multiple variables simultaneously. The app requires data structured with specific fields including key, axis, and value, and supports optional dynamic color styling through hex values. It represents an updated and AppInspect-compliant version of the original Custom Radar Chart Visualization by Scott Haskell, designed to meet current Splunkbase standards. The visualization is useful for displaying data where multiple quantitative variables need to be compared across different categories or dimensions, such as performance metrics, survey responses, or capability assessments.
