This fork of ICE renders a bar chart that shows the average of a detected numeric column grouped by a categorical column, with the data pulled from a remote Gist-hosted CSV file. The code uses d3.csv to load the data, heuristics to pick suitable categorical and numeric columns, and d3.rollups with d3.mean to aggregate the values. The resulting bars are drawn with d3.scaleBand and d3.scaleLinear, and the visualization includes axis labels, rotated category labels, and a grid for easier reading.
