日历热力图，月度数据可视化图表，vue组件
先看效果👇
在线体验https://www.guetzjb.cn/calanderViewGraph/
日历图简单划分为近一年时间，开始时间是 上一年的今天，例如2024/01/01 —— 2025/01/01，跨度刚好一年，依次从上到下看一排真好七个小方格，分别对应着 周日、周一、周二、周三、周四、周五、周六。
PC端、移动端支持良好
方法颜色支持自定义，可根据数据大小规定颜色深度。
实现方式简单易懂~用到element plus和moment，用前请安装到项目
yarn add element-plus moment
# or
npm i element-plus moment
show code

使用方法：
传入size表示方格的宽度和高度，
如果不想要方形，可以自己改样式实现（注意调整外部div高度，必须一排七个，否则周（日、一……六）的顺序会错乱）
<calanderViewGraph :size="10"/>
