I'm excited to share a new open-source Python package I've developed, called Lesley. This package provides an easy way to create calendar-based heatmaps for time-series data, similar in style to GitHub's activity plots.

Lesley includes three primary functions:

cal_heatmap: Generates a calendar-based heatmap for a specified year and dataset, offering a detailed view of daily or weekly activity. month_plot: Creates a heatmap for a specific month, allowing users to drill down into detailed views of their time-series data. plot_calendar: Plots the entire year in a single chart, providing an at-a-glance overview of trends and patterns.

You can explore the source code on GitHub: https://github.com/mitbal/lesley

A live demo is also available online at: https://alexandria-bibliotek.up.railway.app/lesley

I'd love to hear your feedback and suggestions for improvement!
