Coingecko Farming Simulate missing graphics

[PowerPress]

CoinGecko - Farming Simulate section when I follow the example I do not get the graphics just the following below. How can I receive the additional data?

import defi.defi_tools as dft
pair = ['huobi-token','tether']
apr = 45
dft.farmSimulate(pair, apr, start='2021-01-01')
Downloading huobi-token
Downloading tether
{'Token 1': 'huobi-token', 'Token 2': 'tether', 'start': '2021-01-01', 'fixed APR': '45%', 'Buy & Hold': '51.45%', 'Impermanent Loss': '-5.95%', 'Farming Rewards': '84.08%', 'Farming + Rewards - IL': '141.49%'}
