What's the difference between a bar graph and a bar chart?

Nothing meaningful. "Bar graph" and "bar chart" refer to the same thing, a chart that uses rectangular bars to represent data values. "Bar graph" is more common in educational contexts, while "bar chart" shows up more in data visualization and business settings.

What Is a Bar Graph?

A bar graph displays data as rectangular bars where each bar's height represents a value. Bar graphs work best for comparing quantities across categories, like sales by month, scores by team, or votes by candidate.

The bar graph maker above runs a live CoCube component in your browser. CoCube is a modular knowledge base where every element, including charts, is a composable component built from cells and expressions. The bars, buttons, and number editors are all CoCube primitives wired together with event handlers.
