Visual Data
Data tables for the VS Code AI Coding Agent Extensions Sector Radar. All figures are frozen at the 2026-05-17 evidence snapshot and trace to the accepted SC-024 source artifacts.
Display Contract
Reference standard: Operations/SECTOR-RADAR-DISPLAY-STANDARD.md. Unless a row states otherwise, Denominator is In-cluster, N=22. Primary Source is Reports/VISUAL-DATA-VS-CODE-AI-CODING-AGENT-EXTENSIONS.md, with calibration and centroid artifacts listed in the source map.

Cluster Composition
Denominator: In-cluster, N=22. Source: Visual Data Table 1 and calibration role assignments. Reader meaning: role share shows whether the sector is concentrated in leaders, niches, defaults, baseline rows, or boundary cases.

|---|---|---|---|---|
| Category Leader | 5 | 22.7% | In-cluster, N=22 | High adoption, engineering depth, and centroid alignment. |
| Differentiated Niche | 7 | 31.8% | In-cluster, N=22 | Largest role group; meaningful variation survives inside the default. |
| Strong Default | 4 | 18.2% | In-cluster, N=22 | Recognizable default implementations with thinner differentiation. |
| Baseline Implementation | 3 | 13.6% | In-cluster, N=22 | Active package-backed rows with limited independent signal. |
