-一套简单、易用、并具备一定扩展能力和组合能力的统计图表库，基于图形语法理论搭建而成，『G2Plot』中的 G2 即意指图形语法 (the Grammar of Graphics)，同时也致敬了 [ggplot2](https://ggplot2.tidyverse.org/)。我们想做的事有三件：
-
-1. 使用户不用成为可视化专家也能够轻松制作出优雅美观的图表。
-2. 保证图表能够经受得起业务的检验，在真实的场景中易用、好用。
-3. 探索统计图表的更多可能性，使统计图表变得更好玩、更酷。
+G2Plot is an interactive and responsive charting library.
+Based on [the grammar of graphics](https://github.com/antvis/g2), you can easily make superior statistical charts through a few lines of code.

-### 📦 开箱即用、体验优雅的高质量统计图表
+### 📦 Pretty & Lightweight
 
-G2Plot 呈现给用户的是一套提炼自企业级产品的视觉语言和设计规范。不仅对图表的整体视觉样式进行了优化，并且针对每一个图表自身的特点，沉淀出一套最佳配置，保证用户能够通过最少的配置制作出优雅、标准的图表。
+With [AntV](https://antv.vision/en) design principles of data visualization, G2Plot provides standard and elegant visual styles as well as neat config options.

-### 📊 响应式：让图表更聪明
+### 📊 Responsive
 
-在现实的图表应用场景中，一个棘手的难题是图表的展示空间往往并不足够显示图表的数据量，造成极值情况下文本的重叠遮挡、内容无法自适应、内容裁剪等问题。G2Plot 借鉴宽容性设计的思想，在图表的信息密度过高时，对图表辅助信息进行抽稀，保证图表主要信息的展示和基本可读性。
+G2Plot guarantees the readability of the charts in different sizes and data.

-### 🔳 向前一步：会讲故事的图表
+### 🔳 Storytelling
 
-在 G2Plot 体系下，图表不仅仅只是各不相关的实例，图层概念的引入提供了多图表组合、叠加、联动，共同讲述一个数据故事的可能性。未来，我们还将探索统计图表转化信息图的可能性，丰富统计图表的表现能力。
+With the feature of _layers_, charts can be grouped, nested or linked to do exploratory analysis and expressive storytelling.
