Terminal::QuickCharts - Simple charts for CLI tools
use Terminal::QuickCharts;
# Chart routines take an array of data points and return an array of
# rendered rows using ANSI terminal codes and Unicode block characters
.say for hbar-chart([5, 10, 15]);
# Horizontal bar charts support 2D data, grouping (default) or stacking the bars
.say for hbar-chart([(1, 2, 3), (4, 5, 6)], :colors< red yellow blue >);
.say for hbar-chart([(1, 2, 3), (4, 5, 6)], :colors< red yellow blue >, :stacked);
# You can also specify optional style and sizing info
.say for hbar-chart([17, 12, 16, 14], :min(10), :max(20));
.say for smoke-chart(@lots-of-data, :style{ lines-every => 5 });
# auto-chart() chooses a chart variant based on specified semantic domain,
# details of the actual data, and available screen size
.say for auto-chart('frame-time', @frame-times);Comparing an animation's performance before and after a round of optimization:

Terminal::QuickCharts provides a small library of simple text-output charts, suitable for sprucing up command-line reporting and quick analysis tools. The emphasis here is more on whipuptitude, and less on manipulexity.
This is a very early release; expect further iteration on the APIs, and if time permits, bug fixes and additional chart types.
