It uses D3 v6 with SVG rendering, loading CSV data from a GitHub gist. The code employs `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.line` to generate paths for each delay category, with a custom legend and axes drawn using `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b52fda2c4034caab3c481ee94e651be?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
