9 Best Github Style Calendar Heatmap Plugins In JavaScript (2024 Update)

If you are looking for something to visualize the time series data and make it more readable, this article might give you some inspiration.

GitHub, the website that powers software development, uses a contributions calendar to display activity across the month. It's a great way of showing the volume of contribution activity in a given month. This type of calendar also shows users how people contribute to each project, especially how many contributors contribute how many times in a certain period of time. It's quite easy to fall in love with the tool when you start working with it due to its simplicity and fantastic features.

If you want to create a Github contributions calendar-style heatmap graph from your own time series data, one option is to write a jQuery or JavaScript plugin yourself. The other is to find an existing solution. This post compares seven of the best available, so you can sort through them to find the one that works best for your needs. Let's get started.
