<h1>Project 1: US Weather Analysis</h1>
<p id="member">Amber Su, Chi Zhang, Kewei Xu</p>
<p id="description">This project aims to visualize the <b>weather change</b> of three cities:San
Francisco,New York City,and Miami. By examining temperature and humidity trends from 1980-2015, the
visualization seeks to explore the
chronological weather changes across different climate zones and identify potential relationships between
temperature and humidity, as well as their distinct patterns of variation.</p>
