## What it is
Termgraph is a Python command-line tool and library that draws basic charts like bar graphs, histograms, stacked charts, and calendar heatmaps directly in the terminal using Unicode block characters. It reads simple label/value data files or stdin and supports colors, custom tick marks, and emoji.

## Use cases
- draw bar charts in the terminal
- visualize data from a file without a GUI
- render a calendar heatmap in the shell
- quickly chart numeric data from stdin
- add terminal charts to shell scripts
- plot quarterly sales as a terminal bar graph

## When to choose
- you need lightweight terminal-based data visualization with no GUI
- you want to chart data inside shell scripts or CLI pipelines
- you prefer a simple Python library for ASCII/Unicode charts

## When to avoid
- you need interactive, publication-quality, or web-based charts
- you need line/scatter plots or advanced chart types
- your terminal does not support Unicode block characters or ANSI colors
