{"version":"1.0","type":"rich","title":"Pie Chart for USA Flights On-time Performance","description":"This interactive pie chart visualizes USA flight on-time performance by showing departure delay hours for each day of the year. Each slice represents a single day, with the radial length of the slice encoding the delay value. Built with React and D3 v5, the visualization uses D3’s `arc` function to generate the SVG paths, with input data from a CSV file fetched via D3’s `csv` method. The chart is rendered entirely as SVG elements, where each slice’s outer radius is proportional to its corresponding delay metric.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
