What is the main difference between 'stats' and 'chart' commands in SPL?

The distinction between the 'stats' and 'chart' commands in SPL primarily lies in their functionality and output format. The 'stats' command is designed to generate statistical aggregates from your data. It can perform various calculations such as counts, sums, averages, and other statistical functions over specified fields. This command outputs data in a tabular format, which is ideal for further analysis or reporting.

On the other hand, the 'chart' command takes aggregated data and formats it specifically for visualizations. While 'chart' can also perform various statistical computations, such as counts and averages, its primary purpose is to prepare data for graphical representation, allowing users to create visualizations like bar charts, line graphs, or pie charts.

This understanding clarifies that while both commands can work with data aggregation, 'stats' focuses on producing statistical results in a usable format for further analysis, whereas 'chart' emphasizes creating a visual layout of that data.
