{"version":"1.0","type":"rich","title":"Final Project Chloropleth Map","description":"This choropleth map visualizes 2023 barley exports to the US in thousands of metric tons, using a threshold color scale with five green shades to represent export ranges. The map renders country boundaries as SVG paths via `d3.geoPath` with a `d3.geoAlbers` projection, drawing from TopoJSON world-atlas data. Export values are loaded from a CSV and matched to country names, with a `d3.legendColor` legend displaying the categorical scale. The visualization relies on D3 v6 and the d3-legend plugin, with data encoded through `d3.scaleThreshold` and `d3.schemeGreens`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c76799e4456547f8a72fc5188e763b28?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
