A graceful data visualizing library for Golang


If a language can be used to build web scrapers, it definitely needs to provide a graceful data visualizing library. --- by chenjiandongx

In the Golang ecosystem, there are not many choices for data visualizing libraries. The development of go-echarts aims to provide a simple yet powerful data visualizing library for Golang. Echarts is an outstanding charting and visualizing library opensourced by Baidu, it supports adorable chart types and various interactive features. There are many language bindings for Echarts, for example, pyecharts. go-echarts learns from pyecharts and has evolved a lot.
