Termgraph is a terminal data visualization library and command line analytics tool used to render bar charts, histograms, and heatmaps directly in the shell. It utilizes ANSI escape sequences and Unicode characters to generate colorful visual data representations within a text-based environment.
The tool provides specialized capabilities for transforming raw datasets into horizontal or vertical bar graphs, column charts, and stacked charts. It also functions as a heatmap generator, mapping time-series data to a calendar layout to visualize temporal patterns over a year.
The library supports multi-variable data parsing and applies color styling to differentiate between data variables. It employs linear scale normalization and coordinate mapping to translate dataset values into terminal columns and rows.
