{"version":"1.0","type":"rich","title":"Question2","description":"This area chart visualizes Walmart’s total weekly sales over time, aggregated from a CSV dataset. The visualization uses D3.js v6 to load and parse the data, then employs `d3.rollups` and `d3.sum` for aggregation. An SVG area path, generated with `d3.area`, displays the trend, while circles with mouseover events trigger a tooltip showing the exact date and sales figure. Axes are rendered using `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6bf7af07e0d84f27bb98f93fe4ef3bee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
