Line chart is least useful in visualizing categorical data as it depicts the trend of continuous variables over a period of time. Categorical variables cannot be shown as continuous variables on a line chart. Therefore, a bar chart or a Pareto chart would be a better choice for categorical data visualization as it shows the frequency or percentage of categorical variables. A pie chart can also be used, but it is generally less effective than a bar chart.
