{"version":"1.0","type":"rich","title":"World Population Area Chart with D3.js","description":"This example renders a red area chart of world population by year using D3.js v7 and SVG. It loads CSV data from a VizHub dataset, parsing the year column into JavaScript Date objects for a time-based x-axis and the population values for a linear y-axis. The chart employs `d3.area()` with a `curveBasis` interpolation to create the filled shape, along with `d3.axisLeft` and `d3.axisBottom` for labeled axes with a custom tick formatter converting billions. The rendered SVG includes a title, axis labels, and grid lines via tick size extensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f2f45613ebc48959d1db3c5349ea46d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
