I have the following code that should plot a wordcloud of a given text in matplotlib and converts it to plotly:

from wordcloud import WordCloud, STOPWORDS
import matplotlib.pyplot as plt
import plotly.graph_objs as go
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
import plotly.tools as tls

# Thanks : https://www.kaggle.com/aashita/word-clouds-of-various-shapes ##
def plot_wordcloud(text, mask=None, max_words=200, max_font_size=100, figure_size=(24.0,16.0), 
 title = None, title_size=40, image_color=False):
 stopwords = set(STOPWORDS)
 wordcloud = WordCloud(background_color='black',
 stopwords = stopwords,
 max_words = max_words,
 max_font_size = max_font_size, 
 random_state = 42,
 width=800, 
 height=400,
 mask = mask)
 wordcloud.generate(str(text))

 fig = plt.figure()
 plt.imshow(wordcloud)
 return tls.mpl_to_plotly(fig)

word_list = "Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger.[10] Sanger coined its name,[11][12] as a portmanteau of wiki[notes 3] and 'encyclopedia'. Initially an English-language encyclopedia, versions in other languages were quickly developed. With 5,748,461 articles,[notes 4] the English Wikipedia is the largest of the more than 290 Wikipedia encyclopedias.

plot_wordcloud(word_list, title="Word Cloud")

This just returns a blank figure with nothing in the data part:

Figure(
 'data': ,
 'layout': 'autosize': False,
 'height': 288,
 'hovermode': 'closest',
 'margin': 'b': 61, 'l': 54, 'pad': 0, 'r': 43, 't': 59,
 'showlegend': False,
 'width': 432,
 'xaxis': 'anchor': 'y',
 'domain': [0.0, 1.0],
 'mirror': 'ticks',
 'nticks': 10,
 'range': [-0.5, 799.5],
 'showgrid': False,
 'showline': True,
 'side': 'bottom',
 'tickfont': 'size': 10.0,
 'ticks': 'inside',
 'type': 'linear',
 'zeroline': False,
 'yaxis': 'anchor': 'x',
 'domain': [0.0, 1.0],
 'mirror': 'ticks',
 'nticks': 10,
 'range': [399.5, -0.5],
 'showgrid': False,
 'showline': True,
 'side': 'left',
 'tickfont': 'size': 10.0,
 'ticks': 'inside',
 'type': 'linear',
 'zeroline': False
)

Why is that? And how do I fix it?

If I want to plot the matplotlib plot, it works fine - return fig returns a static figure of the wordcloud.

I tried to directly plot the wordcloud in plotly, but with go.Scatter you need to supply the x and y values explicitly - it cannot take them from wordcloud implicitly like plt.imshow can. So, I get a "object is not iterable" error:

def plot_wordcloud(text, mask=None, max_words=200, max_font_size=100, figure_size=(24.0,16.0), 
 title = None, title_size=40, image_color=False):
 stopwords = set(STOPWORDS)
 wordcloud = WordCloud(background_color='black',
 stopwords = stopwords,
 max_words = max_words,
 max_font_size = max_font_size, 
 random_state = 42,
 width=800, 
 height=400,
 mask = mask)
 wordcloud.generate(str(text))


 data = go.Scatter(dict(wordcloud.generate(str(text))),
 mode='text',
 text=words,
 marker='opacity': 0.3,
 textfont='size': weights,
 'color': colors)
 layout = go.Layout('xaxis': 'showgrid': False, 'showticklabels': False, 'zeroline': False,
 'yaxis': 'showgrid': False, 'showticklabels': False, 'zeroline': False)
 fig = go.Figure(data=[data], layout=layout)
 return fig

plot_wordcloud(word_list, title="Word Cloud")

TypeError: 'WordCloud' object is not iterable

If I return wordcloud, it displays this: <wordcloud.wordcloud.WordCloud at 0x1c8faeda748>. If anyone knows how to unpack the wordcloud object so that I can input the x and y parameters from it into go.Figure, that would be great as well (better in fact).

Just to show that unpacking the wordcloud object would work, I can natively plot a wordcloud with plotly by putting random numbers for the x and y values in go.Scatter like so:

import random

def plot_wordcloud(text, mask=None, max_words=200, max_font_size=100, figure_size=(24.0,16.0), 
 title = None, title_size=40, image_color=False):
 stopwords = set(STOPWORDS)
 wordcloud = WordCloud(background_color='black',
 stopwords = stopwords,
 max_words = max_words,
 max_font_size = max_font_size, 
 random_state = 42,
 width=800, 
 height=400,
 mask = mask)
 wordcloud.generate(str(text))


 data = go.Scatter(x=[random.random() for i in range(3000)],
 y=[random.random() for i in range(3000)],
 mode='text',
 text=str(word_list).split(),
 marker='opacity': 0.3,
 textfont='size': weights,
 'color': colors)
 layout = go.Layout('xaxis': 'showgrid': False, 'showticklabels': False, 'zeroline': False,
 'yaxis': 'showgrid': False, 'showticklabels': False, 'zeroline': False)
 fig = go.Figure(data=[data], layout=layout)
 return fig

Its just not the correct wordcloud (obviously, with the positions and sizes of the words correctly defined), which should look like this (the static wordcloud plotted with matplotlib.pyplot):
