Which chart is best for large data?

Scatter plots are best for showing distribution in large data sets.

How do you choose the most appropriate chart?

If you want to compare values, use a pie chart — for relative comparison — or bar charts — for precise comparison. If you want to compare volumes, use an area chart or a bubble chart. If you want to show trends and patterns in your data, use a line chart, bar chart, or scatter plot.
