{"version":"1.0","type":"rich","title":"ICE-6 Marks and Channels","description":"This visualization shows a bar chart comparing the average calorie content of menu items across eight fast-food restaurants, using data from a CSV file with nutritional information. The chart uses steelblue bars to represent each restaurant’s average, with the x-axis listing restaurant names and the y-axis showing calorie values. Built with React and D3 v7, the code employs `d3.scaleBand` for the categorical axis, `d3.scaleLinear` for the numeric axis, and `d3.rollups` to compute the mean calories per restaurant. SVG rendering handles all graphical elements, and axis labels and a title are added through D3’s SVG text functions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dfe0b3748d0942f0a28d2b4c67b1a627?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
