{"version":"1.0","type":"rich","title":"Assignment2 question 2","description":"This example shows a monthly sales trend as a filled area chart, with twelve data points from January through December. The visualization uses D3 v7 to render the chart as SVG, employing `d3.scaleBand` for the month axis, `d3.scaleLinear` for the sales axis, and `d3.area` to generate the semi-transparent steel-blue area path. The chart includes labeled axes for both months and sales values. The sample dataset is hardcoded in the script, and the rendering is handled entirely through D3’s SVG manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2ced386954d40158f76c05eecc6eb10?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
