Chart.js vs Koto: What are the differences?
What is Chart.js? Simple, clean and engaging charts for designers and developers. Visualize your data in 6 different ways. Each of them animated, with a load of customisation options and interactivity extensions.
What is Koto? A D3 charting framework written in ES6. KotoJS is HEAVILY inspired by another reusable charting framework maintained by the Miso Project called d3.chart. I think that project is well designed and well documented. For those who are not familiar with d3.chart, the framework provides a logical way to ensure that all data-visualization components that are authored using the framework are done in a way that facilitates re-usablily.
Chart.js and Koto can be categorized as "Charting Libraries" tools.
Chart.js and Koto are both open source tools. Chart.js with 44.3K GitHub stars and 9.71K forks on GitHub appears to be more popular than Koto with 282 GitHub stars and 15 GitHub forks.
