This AngularJS directive renders an interactive D3 radar chart from CSV data, with controls for toggling axes, levels, polygons, vertices, and legend, plus a faceting option. The visualization uses `d3.svg.line` and `d3.scale.category10` to draw radar polygons and supports custom file uploads or sample datasets like The Avengers. Configuration parameters adjust width, height, level count, and label scaling, while the chart updates via `scope.$watch` on the CSV and config objects.
