{"version":"1.0","type":"rich","title":"Multiple Line Chart of employmentrate","description":"This visualization shows employment rate ratios over time for multiple cities, with each city represented as a colored line. The chart uses d3.line with a curveBasis smoothing function, d3.scaleTime and d3.scaleLinear for the x and y axes, and d3.scaleOrdinal with schemeCategory10 for color mapping. Data is loaded from a CSV file using d3.csv, nested by city with d3.nest, and rendered as SVG paths. A custom colorLegend function displays the city names, while gridlines and axis labels are generated using d3.axisLeft and d3.axisBottom.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6697e6d8bf184b99b628d572f8d2ff78?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
