Axes are built with `d3.axisBottom` and `d3.axisLeft`, scaled by `d3.scaleTime` and `d3.scaleLinear`, and rendered as SVG within a D3 v5 selection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ca2d27db3f084e79804292a258fa8683?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
