echarts VS amcharts4

ECharts was originally a Baidu project, released under https://github.com/ecomfe/echarts (ecomfe = "E-commerce frontend"?). They still maintain some of the auxiliary libraries.

I've been using it since around ... 2018-ish[0]? ... as a replacement for Google Charts. It was my first time using a big library from one of the Chinese tech giants -- basic docs and tutorials in English, then all the advanced stuff (and comments) written in Chinese. I was impressed by how comprehensive the charts library was, and how they'd obviously invested a lot of brainwork into the configuration system. IMO it's one of the highest-quality data visualization libraries in JavaScript unless you're willing to dive deep into something like d3.js.

The blog post's author describes running echarts in a headless Chrome, though, which seems insane to me. It's JavaScript rendering to a -- can't it run in Node with https://github.com/Automattic/node-canvas ?

When working with large datasets, rendering all points in a line chart can cause significant performance issues. For example, plotting 50,000 data points directly can overwhelm the browser and make the chart unresponsive. Tools like amCharts and ApexCharts struggle with such datasets, while ECharts performs better but still isn't optimized for extremely large datasets.

Of course, my bad for not mentioning this. I used JavaScript’s AmChart library to make the visualization. Highly recommend!

It's a cool data-visualization library like Highcharts, Chart.js, amCharts, Vega-Lite, and numerous others. A lot of companies/products including AWS are using it in production.
