Fork of POI Category Tree
This is a tree visualization of ArcGIS point-of-interest categories, showing hierarchical relationships between parent categories like Food, Education, and Shops and Service, and their child values. The layout uses a left-to-right dendrogram with horizontal links, computed via `d3.tree` and `d3.hierarchy`. Category labels are placed with text-anchor adjustments, and the entire view is zoomable through `d3.zoom`. Data is loaded from a CSV file using `d3.csv`, and rendering is done as an SVG, with text shadows improving readability over the link paths.
