Data Visualization Terminal Tools
Data visualization turns numbers into shapes the eye can compare, such as lines, bars, histograms and heatmaps.
Terminal plotters draw with Unicode block characters, braille dots or Sixel graphics, so a chart appears over an SSH session on a machine with no desktop. Typical uses are plotting a column of numbers coming out of a pipeline, watching latency or throughput while a test runs, and reading a flame graph from a profiler.
Below is a list of terminal tools that plot and visualize data.
