{"version":"1.0","type":"rich","title":"area chart","description":"This area chart visualizes monthly customer spending over a year, with a smooth monotone curve connecting values from January through December. The D3.js v7 code uses a band scale for months, a linear scale for spending amounts, and the `d3.area()` generator with `curveMonotoneX` to fill the region beneath the trend line in a semi-transparent teal. Axes are rendered via `d3.axisBottom` and `d3.axisLeft`, with labels for month and spending in dollars. The rendering is SVG-based, driven by the sample dataset defined in `index.js`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/193a6a1e9b3245db9c25656d3f3a8c80?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
