日历热力图，月度数据可视化图表，vue组件

先看效果👇
在这里插入图片描述

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
