Vega: A Visualization Grammar

Vega is a visualization grammar, a declarative format for creating, saving, and sharing interactive visualization designs. With Vega you can describe data visualizations in a JSON format, and generate interactive views using either HTML5 Canvas or SVG.

Vega是一套可视化图形语法，用于声明式地创建、保存和分享可交互的可视化设计。使用Vega，可以使用JSON格式来描述并创建(使用Canvas或SVG)可交互的数据可视化视图。

For documentation, tutorials, and examples, see the Vega website. For a description of changes between Vega 2 and later versions, please refer to the Vega Porting Guide.

了解文档，教程和示例，可以查看Vega website。需要查看最新版本和Vega 2版本之间的详细更改，请移步至Vega Porting Guide。

Are you using Vega in a web application built with a bundler such as Webpack or Browserify? If so, and you do not need server-side rendering support, you might prefer using vega-lib to include Vega in your app. The vega-lib repository also houses our general test suite.

Build Instructions

For a basic setup allowing you to build Vega and run examples:

• Clone https://github.com/vega/vega.
• Run yarn to install dependencies. If you don't have yarn installed, see https://yarnpkg.com/en/docs/install. (If you do not wish to install yarn, you can alternatively run npm install. However, you will not be guaranteed to have dependencies matching those of the current release.)
• Once installation is complete, use yarn build to build output files.

This repository includes the website and documentation in the docs folder. To launch it, run bundle install and bundle exec jekyll serve in the docs folder. The last command launches a local webserver. Now, you can open http://127.0.0.1:4000/vega/ to see the website.

构建Vega并查看示例：

• 克隆Vega库。
• 执行yarn安装依赖。
• 执行yarn build(我本地报错，待验证)

☢️ 翻译补充：执行yarn build进行构建会报错，执行npm run build可以快速解决。

docs文件夹下包含站点和文档文件，如果想运行，在该目录下执行bundle install和bundle exec jekyll serve，然后访问http://127.0.0.1:4000/vega/，即可查看站点。

☢️ 翻译补充：在执行bundle install之前，还需要安装一堆依赖，有点麻烦，可以直接略过。
