{"version":"1.0","type":"rich","title":"MK Line Chart","description":"This dark-themed line chart visualizes monthly sales data from January 2023 through December 2024, sourced from a CSV file. Built with D3 v7, the reusable `lineChart()` function renders an SVG path using `d3.line()` with `curveMonotoneX`, along with circles for data points. Interactive tooltips appear on mouse hover via D3 event handlers. The chart includes a programmatic `update()` method that animates transitions for axes and the line when new data is provided.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f232d0a43fb4fcdac574b5eeb9ba271?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
