create data frame that has the result of the MDS plus the cluster numbers and titles

group by cluster

groups = df.groupby('label')

define custom css to format the font and to remove the axis labeling

css = """

Plot

fig, ax = plt.subplots(figsize=(14, 6)) # set plot size
ax.margins(0.03) # Optional, just adds 5% padding to the autoscaling

iterate through groups to layer the plot

note that I use the cluster_name and cluster_color dicts with the 'name' lookup to return the appropriate color/label

for name, group in groups:

points = ax.plot(group.x, group.y, marker='o', linestyle='', ms=18, label=cluster_names[name], mec='none',
                 color=cluster_colors[name])
ax.set_aspect('auto')
labels = [i for i in group.title]

# set tooltip using points, labels and the already defined 'css'
tooltip = mpld3.plugins.PointHTMLTooltip(points[0], labels,
                                         voffset=10, hoffset=10, css=css)
# connect tooltip to fig
mpld3.plugins.connect(fig, tooltip, TopToolbar())

# set tick marks as blank
ax.axes.get_xaxis().set_ticks([])
ax.axes.get_yaxis().set_ticks([])

# set axis as blank
ax.axes.get_xaxis().set_visible(False)
ax.axes.get_yaxis().set_visible(False)

ax.legend(numpoints=1) # show legend with only one dot

mpld3.display() # show the plot
