Data Visualisation - bubble plots in python

Question

I would like visualise some data stored in a dictionary

foo = {'cat':5, 'dog':1, 'elephant':10}

as a bubble plot, with bubble sizes corresponding to the values. Ideally I would like interactivity; when hovering mouse over bubble you see the name 'cat', for example.

Any recommendations and tips for how to achieve this?

An idea I had is to create a pandas dataframe, df =

 Animals Love x y 0 cat 5 0 0 1 dog 1 1 0 2 elephant 10 0 1

where the x, y parameters are used to tell something like seaborn the location of the bubbles, and the 'Love' determines the size of the bubbles. This feels somewhat clunky, especially as I have many more than 3 rows. I would like it if the locations of the bubbles were chosen automatically.

Of course, this is just one idea, so any suggestions are very welcome!

I haven't found a simple way to do it with matplotlib but if you don't mind a browser display you can try mpld3. Here is an example:

import matplotlib.pyplot as plt import numpy as np import mpld3 fig, ax = plt.subplots(subplot_kw=dict(axisbg='#EEEEEE')) N = 10 # Animals Love x y # 0 cat 5 0 0 # 1 dog 1 1 0 # 2 elephant 10 0 1 x = np.array([0, 1, 0]) y = np.array([0, 0, 1]) s = np.array([5, 1, 0]) * 1000 # make circle looks bigger c = np.array(['red', 'green', 'blue']) labels = ['cat', 'dog', 'elephant'] scatter = ax.scatter(x, y, c=c, s=s, alpha=0.3) ax.grid(color='white', linestyle='solid') ax.set_title("Scatter Plot (with tooltips!)", size=20) tooltip = mpld3.plugins.PointLabelTooltip(scatter, labels=labels) mpld3.plugins.connect(fig, tooltip) mpld3.show()

Result (label shown on hover):

You can use the bokeh python library for interactive visualization.

Combine the hover functionality in figure and plot circles/bubbles in place of rectangles as in the above tutorial.
