ECharts vs Koto: What are the differences?
Developers describe ECharts as "*A free, powerful charting and visualization library *". It is an open source visualization library implemented in JavaScript, runs smoothly on PCs and mobile devices, and is compatible with most current browsers. On the other hand, Koto is detailed as "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.
ECharts and Koto can be categorized as "Charting Libraries" tools.
ECharts and Koto are both open source tools. It seems that ECharts with 35.7K GitHub stars and 10.8K forks on GitHub has more adoption than Koto with 281 GitHub stars and 15 GitHub forks.
