{"version":"1.0","type":"rich","title":"Assignment2Question2","description":"This example shows a 2,400-pixel-wide area chart of New York City monthly temperatures across years, with red circular markers at each data point that reveal a tooltip on hover. The visualization uses D3 v7 to load CSV data from a GitHub gist, parse the Temperature column, and render an SVG path via the `d3.area` generator with `d3.scaleBand` and `d3.scaleLinear` axes. The tooltip is implemented as an HTML div that transitions opacity on `mouseover` and `mouseout`, while the chart includes rotated axis labels and a steelblue fill. The code runs in a plain HTML page with inline CSS for the container and tooltip styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/87771f7fcb1441a693147112c985041a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
