sns.countplot("Embarked",data=data_T,ax=ax[0,0])
ax[0,0].set_title("No.Of Passengers Boarded")

sns.countplot("Embarked",hue="Sex",data=data_T,ax=ax[0,1])  
ax[0,1].set_title("Male-Female Spilt for Embarked")

sns.countplot("Embarked",hue="Survived",data=data_T,ax=ax[1,0])
ax[1,0].set_title("Embarked vs Survived")

sns.countplot("Embarked",hue="Pclass",data=data_T,ax=ax[1,1])
ax[1,1].set_title("Embarked vs Pclass")
