Bar

If you’re not sure which chart to use, start here with the classic bar chart. Most of the time, bar charts will be an excellent choice for your dataset.

Some data visualization gurus will argue that bar charts should only be used for a single point in time rather than to display patterns over time – in that case, they’d suggest you use a line chart instead. My advice: focus on your audience and choose a chart type that will be easiest for them to understand.
