# usage: htype: define the heart type, inside: define the elements in heart shape,
#   outside: define the elements ouside the heart shape, width and height define the heart size.

# more: width:height=1:1 is suggested when chinese characters was used, and width:height =2:1 in other cases   

# eg type 0
# plot_heart(htype=0,inside="你",outside="我")

# eg type 1
# plot_heart(htype=1,inside="You",outside="I",width=120,height=60)
