Rendered as an SVG using D3 v5, the visualization employs `csv` to load data, `scaleLinear` for the x-axis, `scaleBand` for the y-axis dates, and `axisLeft`/`axisBottom` for axes. Bars are drawn with `rect` elements, while a light-blue background and lavender fills enhance readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5a5b3bbf0f05468ea1aee7966ed1d0f1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
