Basic Bar Chart
This example shows a grouped bar chart comparing daily temperature readings across New York, San Francisco, and Austin over three months. The chart is rendered as an SVG using D3 v4, with three bars per date—one for each city—colored distinctly and labeled in a legend. Data is loaded from a tab-separated values file, and the visualization includes axes for dates and temperature values. The bars are positioned side by side using a d3 scaleBand for the date categories and a linear scale for the temperature range.
