The chart uses a monotone curve to smooth transitions between points, with a steelblue filled area beneath the line. The code loads CSV data via `d3.csv`, aggregates counts with `d3.rollups`, and renders the SVG using `d3.area`, `d3.scalePoint`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7e62f01c64cc4a0da21cdd38d2885e12?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
