{"version":"1.0","type":"rich","title":"San Francisco Temperature - Area Chart with Zero Baseline","description":"This area chart visualizes world population growth from historical data, using a zero-baseline y-axis to emphasize proportional changes over time. The D3 v5 code loads CSV data and renders an SVG path generated with `d3.area()` and `curveBasis` for smoothing. Axes employ `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft`, with tick lines spanning the chart. The visualization includes labeled titles and formatted tick values, converting billions with `d3.format`. The chart’s filled blue area and line stroke clearly highlight the upward population trend across the displayed years.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/be3d767873744facb7b4fac56478623f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
