Why a ggplot is not showing here?

I am using code from here trying to produce a simple plot:

from lets_plot import *
LetsPlot.setup_html()        

import numpy as np
np.random.seed(12)

data = dict(
    cond=np.repeat(['A','B'], 200),
    rating=np.concatenate((np.random.normal(0, 1, 200), np.random.normal(1, 1.5, 200)))
)

ggplot(data, aes(x='rating', fill='cond')) + ggsize(500, 250) \
+ geom_density(color='dark_green', alpha=.7) + scale_fill_brewer(type='seq') \
+ theme(axis_line_y='blank')

I am running this code from a standalone file using command line:

python3 mycode.py

It runs without any error but no plot shows up. I have also tried following but it does not work:

gg = ggplot(....
print(gg)

Above outputs data and layers on console but no plot is shown.

Adding following also does not help:

import matplotlib.pyplot as plt

Where is the problem and how can I get a plot to be displayed with above code?

The package seems to depend on JavaScript(JS) for displaying visulisations and seems to be built to supprt online notebooks as it says on the github page - Lets-Plot meant for

However, there does seem to be a plugin available for pycharm and IntelliJ IDEA but the one on pycharm is available only in professional version.

So with this new information, I have tried running an instance of Jupyter notebook online and running the same piece of code produces the graph is expected.
