{"version":"1.0","type":"rich","title":"Line Chart with multiple lines","description":"This visualization shows a week of temperature readings from multiple cities, with each city represented as a colored line to reveal comparative trends. The chart uses a time-scaled x-axis, a linear temperature y-axis, and an ordinal color scale, with a custom legend displayed on the right. The code relies on d3.csv, d3.nest, d3.line with d3.curveBasis, and d3.axisBottom/axisLeft to render the SVG. Data is loaded from an external CSV file containing timestamp and temperature values, with gridlines drawn through tick sizing and stroke styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b2bb81d1d3d64ef29f95ebb332eef3c3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
