{"version":"1.0","type":"rich","title":"World population Area Chart","description":"This area chart visualizes San Francisco temperature trends over time, using a green smooth curve against a white background. Built with D3 v5, it loads CSV data from VizHub and maps timestamps to a time scale and temperatures to a linear scale. The visualization includes styled axes with tick marks, grid lines, and rotated labels for the y-axis, while the x-axis displays time ticks and a title. The line is generated using `d3.line` with `curveBasis` for smoothing, and rendered as an SVG path with custom CSS styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1b9a382e32a0486cb46e973a9d253796?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
