`PlotlyChart`¶

Render a Plotly figure through Hedron's bounded adapter pipeline.


Import	`from hedron import PlotlyChart`
Distribution	`hedron-charts[plotly]`
Backend activity	No
Normal render mode	`RenderMode.FRAGMENT`

Live demo¶

PlotlyChart outputAccessible static preview with a text conclusion.

The preview is a local docs simulation (not a running Hedron server). Interactive demos show a “Simulated HTMX” trace when applicable.

Install the optional provider before importing this component:

pip install "hedron-charts[plotly]>=0.1.0,<0.2"

Basic use¶

from hedron import PlotlyChart

component = PlotlyChart(fig, title='Requests by region', description='US East handles the largest share.')

Compose under Page for full documents, or return from a fragment route for HTMX swaps.

How it works¶

The adapter compiles the figure into the supported static or browser representation, enforces visualization limits, and attaches accessible metadata and fallback content.

This component's core behavior is server-rendered HTML and does not require a browser runtime. The preview is ordinary semantic HTML, so keyboard, form, link, and disclosure behavior comes from the platform.

Constructor and parameters¶

PlotlyChart(figure, *, title=None, description=None, alt=None, waiver=None)

Parameter	Type	Meaning
`figure`	`Plotly figure`	Figure specification.
`title / description / alt`	`str \| None`	Accessible metadata.
`waiver`	`str \| None`	Reviewed exception.

Composition and backend behavior¶

Keep PlotlyChart at the smallest semantic boundary. Fragment routes should return only the replaced region and preserve stable target IDs across success, validation, empty, loading, and error responses.

This component is primarily presentational; keep any mutation on an explicit action or component route.

Accessibility¶

Make hover-only values available through labels or a table and ensure keyboard users can reach any enabled controls.

Security¶

Escaping and SafeUrl / TrustedHtml are framework concerns; authorization and data exposure remain application code. Redact secrets before rendering.

Common mistakes¶

Do not pass untrusted custom HTML, JavaScript callbacks, or unbounded traces.
Do not copy docs-preview JavaScript into an application server.

Testing¶

from hedron import RenderMode, render

result = render(component, mode=RenderMode.FRAGMENT)
assert result.html
assert not result.diagnostics
