Charty: Statistical data visualization in Ruby

Have you ever thought it would be better to make stylish charts by Ruby for daily data visualization tasks that sometimes occur? I will make that wish come true! Using Charty, you can do it by Ruby.

Charty makes statistical data visualization easier. If you want to put error bars in a bar plot, you must calculate the mean and the 95% confidence interval before plotting. Charty performs these calculations instead of you. Moreover, Charty can recognize many data types as table data and supports files, Jupyter Notebook, JupyerLab, VSCode, and a terminal emulator as the output destination.
