             Summary: Compact SQL plan visualization with detail side panel
                 Key: SPARK-55786
                 URL: https://issues.apache.org/jira/browse/SPARK-55786
             Project: Spark
          Issue Type: Improvement
          Components: Web UI
    Affects Versions: 4.2.0
            Reporter: Kent Yao


Improve the SQL plan visualization on the execution detail page by making node labels compact (operator name only) and adding a clickable detail side panel that shows full metrics.

Key changes:
- Node labels show only operator name (plain text, no HTML)
- Cluster labels shortened to (N) / duration format
- Right-side panel shows metrics table on node click
- Cluster click shows cluster metrics + all child node metrics
- Metrics rendered as structured tables using metricType (size/timing/average)
- Panel collapses together with Plan Visualization section
- Cluster padding and spacing optimized for compact layout

Part of the Web UI modernization umbrella SPARK-55760.
