graph-cli

Offers extensive command-line flags for detailed customization, as shown in the examples with options like --hist, --resample, and the separate OPTIONS.md file for full documentation.

Supports chaining multiple CSV files in commands, enabling complex multi-source visualizations without extra scripting, demonstrated in the sine-cosine example with --chain.

Includes a resampling feature to aggregate or downsample data, making time-series plots cleaner, as evidenced by the avocado.csv example with --resample 1W.

Easy installation via pip and reasonable defaults allow immediate use with minimal arguments, such as in the basic sine.csv example requiring only input and output flags.
