The chart that is not suitable for continuous data is the Pie Chart. This type of chart is used to display a set of categories, and as such is best used for categorical data. Continuous data refers to measurements that can take on any value (or a limited set of values) within a given range. Examples of continuous data include temperature, height, distance, speed, and any other data that cannot be easily and accurately categorized. For visualizing continuous data, the best chart types to use would be Line Charts, Bar Graphs, and Scatter Plots.
