{"version":"1.0","type":"rich","title":"world population area chart","description":"This visualization presents global population changes over time with a smooth area chart, using a time-scaled x-axis and a linear y-axis that displays population in billions. The chart is built with D3.js, leveraging the `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `area` functions to generate the SVG path. The area is filled in maroon with a basis curve, and the y-axis labels are formatted using a custom tick format that converts values to billions. Data is sourced from a CSV file containing world population figures by year.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2cb7540e2f004cb7ad9f7af48fec9e26?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
