📣 Announcing Dash Sunburst

:wave: Hey Dash Club –

We’ve just created a set of tutorials to help Dash component plugin authors reconcile the differences between D3.js and React (Integrating D3.js into Dash Components | Dash for Python Documentation | Plotly). As part of these tutorials, we made a few D3.js components that are functional on their own. One of these is the Dash Sunburst component.

Connecting these sunburst charts to Dash is really cool because it enables simple server-side updates via Dash callbacks. If your data is large, e.g. if you are viewing hundreds of layers, then a sunburst chart can quickly become incomprehensible. With Dash, you can update the chart from the Python backend, enabling you to progressively explore the radial network:

Thank you very much for this. How can I download this package to use for dash? I am trying pip install dash_sunburst, but it is not working. Is there a link that you can possibly provide? thanks

Everything explained here :https://plot.ly/python/v3/sunburst-charts/

This does not help me with downloading the dash_sunburst package. I cannot use go.Sunburst for some reason because when I run the program, the graph will not appear.

Actually, it is very straightforward to download and use it, took only five minutes.
However, I could not enlarge and shrink the size of a sunburst graph. Anyone can help this.

FYI - We have two sunburst implementations now.

  1. This post outlined a custom sunburst created from scratch with D3 as a separate Dash plugin. It’s intent was as much a tutorial on how to use D3 in a Dash component as it was to have a useful standalone chart type.
  2. After we released this custom component, we took what we learned and created a 1st class dcc.Graph chart type. This was done by updating plotly.js, the underlying graphing library that powers Dash & the Plotly’s Python graphing library (plotly.py).

We recommend using the official dcc.Graph chart type - It has more features and will get more attention from us on the development side of things. This chart type is documented here: https://plot.ly/python/sunburst-charts/

Thanks for Chriddyp for this updated information. However, I could not make one of the simple example from /pyton/sunburst to work on dash. Here are my codes and error message:

import dash
from dash.dependencies import Input, Output
import dash_core_components as dcc
import dash_html_components as html
import plotly.graph_objs as go

app = dash.Dash(’’)

app.scripts.config.serve_locally = True

app.css.config.serve_locally = True

app.layout = html.Div([
html.Div(id=‘output’, style={‘clear’: ‘both’}),

@app.callback((Output(‘sun’, ‘figure’), Input(‘output’, ‘data’)))
def updatesun(data):
fig = go.Figure(go.Sunburst(
labels=[“Eve”, “Cain”, “Seth”, “Enos”, “Noam”, “Abel”, “Awan”, “Enoch”, “Azura”],
parents=["", “Eve”, “Eve”, “Seth”, “Seth”, “Eve”, “Eve”, “Awan”, “Eve”],
values=[65, 14, 12, 10, 2, 6, 6, 4, 4],
fig.update_layout(margin=dict(t=0, l=0, r=0, b=0)),
return fig

if name == ‘main’:

dash.exceptions.IncorrectTypeException: The output argument output.data must be of type dash.Output.

Please let me know what I need to make the dash work. Thanks/


Never mind, I figured out how to plot it by following the plotly documentation. Thanks.

A post was split to a new topic: go.Sunburst vs px.Sunburst
