Bar Chart
A chart that uses rectangular bars to represent data values, with bar length proportional to the value.
Bar charts are ideal for comparing discrete categories. Vertical bars (column charts) work well for time series with few points. Horizontal bars are better for long category labels. Grouped bars compare multiple series; stacked bars show part-to-whole within categories.
