Grouped Radar Chart Display for Driving Evaluation Visibility

The patent segments the multiple evaluation items into hierarchical groups (e.g., safety, efficiency, comfort categories) and displays aggregated scores for each group on the radar chart. This segmentation allows comprehensive evaluation coverage while maintaining visual clarity by reducing the number of individual items displayed from potentially dozens to just a few key categories.

The patent combines multiple individual evaluation items into unified display groups, where each group represents a category of related items. The radar chart then displays one aggregated score per group rather than separate scores for each individual item, merging redundant visual elements while preserving the comprehensive evaluation information.

The patent segments evaluation items into logical groups and displays aggregated scores for each segment on the radar chart. Detailed information about individual items within each group is preserved and can be accessed through interactive elements or supplementary displays, maintaining information completeness while reducing visual complexity.

The patent transitions from a two-dimensional display of numerous individual items to a hierarchical structure where the radar chart displays aggregated group scores in one dimension, while detailed item information is organized in additional dimensions (such as expandable sections, tooltips, or separate detailed views), reducing visual clutter while preserving detail.
