{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays a week of temperature readings from multiple cities, using color to distinguish each city's time series. The visualization is rendered as an SVG using D3 v5, with a time-based x-axis and linear temperature scale. The code applies a basis curve to smooth the lines, nests the data by city, and includes a categorical color legend. Data is loaded from a CSV of global temperature measurements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f577075c8f984067a2e528085b0b40c1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
