The SVG chart uses `scaleTime` for the x-axis and `scaleLinear` for the y-axis, with custom `AxisBottom` and `AxisLeft` components rendering ticks and labels. Data is loaded asynchronously via `d3.csv` from a GitHub gist, with the y-axis formatted in compact notation and tooltips showing the month via the native SVG `<title>` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b85a0b5857bc4ef7b35e8a2981595f1f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
