{"version":"1.0","type":"rich","title":"part_2act_7","description":"This example visualizes sales and expenses data over time as an area chart, using a linear gradient fill to emphasize the trend in sales figures. The chart is rendered as an SVG, with the dataset loaded from a GitHub-hosted CSV file via `d3.csv`. The code utilizes D3.js v7 APIs including `d3.scaleLinear` for axis scaling, `d3.axisBottom` and `d3.axisLeft` to generate tick marks, and `d3.area` to create the filled path under the curve. Axes are labeled to clarify the variables plotted.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2eaad67cde67403ba4a9ed8960f2cdd1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
