import graph_widget
import pandas as pd
import json
import requests

url = "https://raw.githubusercontent.com/observablehq/sample-datasets/refs/heads/main/miserables.json"
response = requests.get(url)
data = response.json()

repulsion_slider = mo.ui.slider(
    start=-100, stop=500, step=10, value=1, debounce=False, label="Repulsion"
)
node_scale_slider = mo.ui.slider(
    start=1, stop=20, step=1, value=3, debounce=True, label="Node scale"
)
colour_feature_dropdown = mo.ui.dropdown(
    options=list(data["nodes"][3].keys()), value="kind", label="Colour by"
)
colour_scale_type_radio = mo.ui.radio(options=["diverging", "sequential"], value="diverging", label="Colour scale type")

data_graph = mo.ui.anywidget(
    graph_widget.ForceGraphWidget(
        data=data,
        repulsion=2,
        node_scale=2,
        colour_feature="",
        colour_scale_type=""
    )
)

data_graph.repulsion = repulsion_slider.value
data_graph.node_scale = node_scale_slider.value
data_graph.colour_feature = colour_feature_dropdown.value
data_graph.colour_scale_type= colour_scale_type_radio.value

mo.hstack([data_graph,
    mo.vstack([
        repulsion_slider,
        node_scale_slider,
        colour_feature_dropdown,
        colour_scale_type_radio])], justify="start")

selected = data_graph.selected_ids

Arguments

• repulsion
• node_scale
• colour_feature
• colour_scale_type: can be empty string, or "diverging"

Development

We recommend using uv for development. It will automatically manage virtual environments and dependencies for you.

uv run marimo edit example.py

Changes made in src/graph_widget/static/ will be reflected in the notebook.
