“bar graph” vs “histogram” — What’s the Difference?

A bar graph compares values across distinct categories (cars, bikes, buses) — bars have gaps between them and the order can change. A histogram shows the distribution of one continuous numeric variable across ranges or bins (heights 150-160, 160-170 cm) — bars touch each other and the order is fixed by value.
