Bubble Chart –

A bubble chart is a scatter plot in which a third dimension of the data is shown through the size of markers.

To create a Bubble chart we will use the gapminder data. So, Let’s read the data first.

import as px

df =

Let’s check the minimum and maximum year in the dataframe.

print("Min Year: ", df['year'].min())
print("Max Year: ", df['year'].max())
Min Year:  1952
Max Year:  2007

Let’s create a Bubble chart for the year 2007

# select only 2007 data
df_2007 = df[df['year']==2007]

1 . Create a Bubble Chart with Plotly Express –

Let’s create a bubble chart with plotly express which makes it easy to create various kinds of plots easily in plotly.

We will plot gdpPercap on the x-axis and lifeExp on the y-axis. We will use the pop column for the size of the markers and use the continent column for the color parameter to distinguish between different continents.

fig = px.scatter(df_2007, x='gdpPercap', y='lifeExp',size='pop', 
                 color='continent', log_x=True, size_max=60)

2 . Create an animated Bubble Chart with Plotly Express –

We can also create an animated bubble chart using plotly express. To create an animated bubble chart we need to use the animation_frame and animation_group arguments.

fig = px.scatter(df, x="gdpPercap", y="lifeExp", animation_frame="year", 
                 animation_group="country", size="pop", 
                 color="continent", log_x=True, size_max=55)
