## What is this PR about? Phase 4 of [GH-2678](https://github.com/apache/sedona/issues/2678): Add SVG visual illustrations for all **21 measurement functions**. ### Changes - **21 new SVG files** in `docs/image/ST_<Name>/ST_<Name>.svg` - **63 updated doc files** (21 SQL + 21 Flink + 21 Snowflake) with image references ### Functions covered | Category | Functions | |----------|-----------| | Distance | ST_Distance, ST_3DDistance, ST_DistanceSphere, ST_DistanceSpheroid, ST_FrechetDistance, ST_HausdorffDistance, ST_MaxDistance | | Closest/Longest | ST_ClosestPoint, ST_LongestLine, ST_MinimumClearance, ST_MinimumClearanceLine | | Area | ST_Area, ST_AreaSpheroid | | Length | ST_Length, ST_Length2D, ST_LengthSpheroid | | Perimeter | ST_Perimeter, ST_Perimeter2D | | Angle | ST_Angle, ST_Azimuth, ST_Degrees | ### Visual style - **Distance**: Two geometries (blue A, red B) with dashed green measurement line and arrows - **Area**: Polygon with green highlighted fill and "- **Area**: Polygon with green highlighghlighted in green with "Leng- **Area**: Polygon with green highlighted fill and "- **Area**: Polygon with green highlighghlighted in green with "Leng- **Area**: istance line to - **Area**: Polygon with green highlighted fill and "arthest points - **Angle**: Rays with green angle arc annotation - **Fréchet/Hausdorff**: Coupling lines between corresponding vertices ### Image placement Images are inserted after the complete Introduction section and before the Format line, consistent with Phases 1-3. Multi-line introductions (with notes, tips, warnings) are handled correctly — image is placed after the full intro block.
