3D Bubble Charts in Julia

How to make 3D Bubble Charts in Julia with Plotly. Three examples of 3D Bubble Charts.


3d Bubble chart with Plotly Express

using PlotlyJS, CSV, DataFrames

df = dataset(DataFrame, "gapminder")
trace = scatter3d(
    df,
    x=:year,
    y=:continent,
    z=:pop,
    mode="markers",
    marker=attr(
        size=:gdpPercap,
        color=:lifeExp,
        sizeref=maximum(df.gdpPercap) / 60^2,
        sizemode="area"
    )
)

layout = Layout(scene_zaxis_type="log")
plot(trace, layout)

Simple Bubble Chart

using PlotlyJS, CSV, DataFrames, HTTP

df = CSV.File(
    HTTP.get("https://raw.githubusercontent.com/plotly/datasets/master/gapminderDataFiveYear.csv").body
) |> DataFrame

start = 750
stop = 1500

trace = scatter3d(
    x=df[!, "year"][start:stop],
    y=df[!, "continent"][start:stop],
    z=df[!, "pop"][start:stop],
    text=df[!, "country"][start:stop],
    mode="markers",
    marker=attr(
        sizemode="diameter",
        sizeref=750,
        size=df[!, "gdpPercap"][start:stop],
        color=df[!, "lifeExp"][start:stop],
        colorscale="Viridis",
        colorbar_title="Life<br>Expectancy",
        line_color="rgb(140,140,170)"
    )
)

layout = Layout(height=800, width=800, title="Examining Population and Life Expectancy Over Time")

plot(trace, layout)

Bubble Chart Sized by a Variable

Plot planets' distance from sun, density, and gravity with bubble size based on planet size

        size = planet_diameter,
        color = planet_colors,
        )
)

    width=800,
    height=800,
