rc('font', family=font_name)

# import matplotlib.pyplot as plt

confirmed = pd.read_csv('./data/daily_Confirmed.csv', index_col = ['Date'])

#pd.read_csv('./data.csv', encoding='utf-8') #Default(기본)

#pd.read_csv('./data.csv', encoding='cp949') #11172자

#pd.read_csv('./data.csv', encoding='euc-kr') #2350자
