{"version":"1.0","type":"rich","title":"New line chart","description":"This chart visualizes Finnish population data, comparing the number of deaths and live births per year as smoothed line paths over time. A color legend distinguishes the two categories, with both lines rendered using an SVG path generated by D3’s `line` and `curveBasis` functions. The visualization uses `d3.scaleUtc` for the time axis, `scaleLinear` for the population counts, and `axisBottom`/`axisLeft` for gridlines and ticks. Data is loaded from a CSV file and scaled to thousands, with a title and axis labels included.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0c13b0a5145f400b8093e69e62c59220?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
