题目说的不对，准确的说这个图叫概率密度分布。
输入一组数据，画出这组数据的概率密度函数曲线。
在图像处理中，可以用来表现像素的分布情况，与直方图功能类似。
The title is not quite right — to be precise, this plot is called a probability density distribution.
Given a set of data, plot the probability density function curve of the data.
In image processing, it can be used to show the distribution of pixels, similar in function to a histogram.

摸鱼时光发现了一篇折腾 VPS 的博客，上面写着用 nginx 反代 GitHub，可以用于 GitHub 的下载加速，并且说理论上可以做任何网站的镜像。于是我也简单操作了一下。
During my idle time I found a blog post about tinkering with VPS. It described using nginx to reverse-proxy GitHub to speed up downloads from GitHub, and claimed that in theory you could mirror any website. So I went ahead and gave it a simple try.
