Density Field Animation¶

Animates the internal density field using animate_density_field.

Build the cartogram with snapshot

import carto_flow.data as examples
import carto_flow.flow_cartogram as flow
from carto_flow.flow_cartogram.animation import animate_density_field

gdf = examples.load_us_census(population=True)

cartogram = flow.morph_gdf(
    gdf,
    "Population",
    options=flow.MorphOptions.preset_balanced().copy_with(
        n_iter=250,
        snapshot_every=5,
        area_scale=1e-6,
        show_progress=False,
        save_internals=True,
    ),
)

Animate the morphing snapshots.

anim = animate_density_field(
    cartogram,
    duration=2.0,
    fps=15,
    show_axes=False,
    figsize=(8, 5),
    density=flow.DensityPlotOptions(
        colorbar_kwargs={"shrink": 0.7},
        normalize="ratio",
    ),
)

Total running time of the script: ( 0 minutes 8.162 seconds)
