This prompt guides the creation of a Python script using the QGIS Python API (PyQGIS) to seamlessly add a GeoJSON file as a new layer in QGIS. The script ensures that the vector layer is properly loaded, preserving attributes and geometry, and is automatically added to the QGIS project for visualization and analysis.
It is ideal for GIS professionals, developers, and data analysts who want to automate layer management in QGIS without manually importing files. By using this prompt, users can qui
