{"version":"1.0","type":"rich","title":"Attachment – GDAL","description":"A 3D GeoJSON LineString from an EPSG:21781 coordinate system is rendered as a spatial attachment in a GDAL ticket. The example uses D3’s `d3.geoPath` to project the geographic coordinates onto a 2D canvas, while the third dimension (elevation) is mapped to visual depth or height. The code demonstrates handling of 3D geometries in GeoJSON, with the line’s vertices drawn as a connected path. It relies on standard D3 projection and path APIs to visualize the data, which is sourced from a GDAL issue attachment.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8393683?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
