{"version":"1.0","type":"rich","title":"Temperature in multiple cities","description":"This visualization shows population trends over time for multiple cities. A line chart displays each city’s population as a colored line, with a color legend identifying them. A vertical line marks the currently selected year, and moving the mouse across the chart updates that selection. The code builds the SVG using D3 v5, employing `d3.scaleOrdinal` with `schemeCategory10` for colors, `d3.axisBottom` and `d3.axisLeft` for axes, `d3.line` with `curveBasis` for smoothing, and `d3.mouse` for interaction. Data is loaded from a CSV file using `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a372f6fe189443009a98145e286c2e87?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
