{"version":"1.0","type":"rich","title":"d3 map experiment with NZTM","description":"This experiment uses D3 v4 to render New Zealand’s census ward boundaries as a static SVG map. The geographic data is sourced from Stats NZ, converted from the NZTM projection (EPSG:2193) into a quantized TopoJSON format via a Makefile-driven pipeline, then displayed with a null projection so coordinates are used as-is. The map uses a light grey fill for land areas and omits internal boundaries, showing only the outer ward outlines. The code includes a commented-out geoTransform for potential scaling/zooming and a commented-out boundary mesh, suggesting the visualization focuses on the raw spatial layout of New Zealand's wards.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-faa02be104b53949257e70c2debf7a7f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
