{"version":"1.0","type":"rich","title":"Untitled","description":"This visualization shows the cumulative growth of a dataset from 1949 to 2019, tracking a running total that increases from 5 to nearly 15,000 over seven decades. The data is loaded from a CSV file using D3’s `csv()` function, though the rendering logic is incomplete in the provided `index.js`. The example demonstrates how to import and parse tabular data with D3 v3, including accessing SVG dimensions via `.attr()` and preparing the data for subsequent plotting. The chart’s design and marks are not yet implemented in the visible code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/677facb038fe47019ad9a101ac59b1a0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
