{"version":"1.0","type":"rich","title":"Iteration 1","description":"This radar chart compares four institutional metrics—total enrollment, endowment per student, annual R&D expenditures, and selectivity—across thirteen universities. The visualization uses a square layout with linear scales positioned around the chart’s edges, drawing each university as a closed polygon path via `d3.line()`. Interactive features include hover highlighting that emphasizes matching polygons and legend items, plus clickable legend entries that toggle universities on and off. The code leverages D3 v7 APIs such as `scaleLinear`, `scaleOrdinal`, `axisLeft`, `axisBottom`, and event handlers on SVG elements, with data loaded from a CSV using `csvParse`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a452cd9549b14ca8a48e433ede3c9b0f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
