首先用ai画一个简单的风车
例如：
svg代码：
<animateTransform
attributeName="transform"
begin="0s"
dur="2s"
type="rotate"
from="0 305 225.5"
to="360 305 225.5"
repeatCount="indefinite"
/>
接下来看完整的代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style>
svg{
500px;
height: 800px;
border: 1px solid #ccc;
display: block;
margin: 0 auto;
}
</style>
</head>
<body>
