疫情统计可视化（一）升级版

任务：

1.第一阶段目标：

导入全国疫情数据库payiqing.sql（MySQL数据库）。

可以按照时期查询各个省市的疫情统计表格。

以折线图或柱状图展示某天的全国各省的

2.第二阶段目标：疫情统计地图可视化：可以通过地图的形式来直观显示疫情的大致分布情况，还可以查看具体省份的疫情统计情况。

在全国地图上使用不同的颜色代表大概确诊人数区间，颜色的深浅表示疫情的严重程度，可以直观了解高危区域；

鼠标移到每个省份会高亮显示、点击鼠标会显示该省具体疫情情况、点击某个省份显示该省疫情的具体情况

显示该省份对应的感染患者人数、疑似患者人数、治愈人数、死亡人数；确诊人数。

3.第三阶段目标：鼠标移到每个市会高亮显示，并且显示简单的数据；

数据下钻：单击各个省可以下钻到各个地市的数据显示。
