After that, you should calculate the correlations between the exchange rates of the currencies and visualize them, Which currencies had the highest positive/negative correlation? Which currencies were not correlated, or had a low correlation?
描述 ：你正在做关于交易和不同货币的研究，你的任务之一是比较1980年至1998年美元对其他8种货币的每日汇率。由于工作日的公共假期，数据包含一些缺失值，你应该首先使用你选择的策略来处理这些缺失值。之后，你应该计算这些货币的汇率之间的相关性，并将其可视化，哪些货币的正/负相关性最高？哪些货币不相关，或者相关度低？
