我正在制作一个投影仪演示文稿，想展示一些世界各国的数据分析图像。在地图图像中创建超链接是否可行？
我理想情况下想要一张世界地图，按如下方式勾勒出每个国家/地区的轮廓；我没有数据的国家/地区将为空白，而我有数据的国家/地区将填上红色。我希望能够单击每个红色国家/地区以自动转到包含我的数据分析图像的幻灯片（使用数据幻灯片上的投影仪按钮返回世界地图）。
这可行吗？
答案1
一个不太漂亮的解决方案可能是以下内容（代码中有更多信息）：
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{svg.path,math}
\tikzset{mapScale/.style={scale=0.5,yscale=-1}}% in the svg file the coordinate are upside down therefore yscale=-1
%Europe countries borders (for a more clean code this can be put in a separete file)
%the svg file with the borders coordinates is take from https://simplemaps.com/resources/svg-europe
%open the file with a text editor and copy and paste the boreder of the nation of interest
%Italy
