Customer journey graph

Customer journey graph uses Fission Charts typed Rust data to render a production-ready hierarchy view. Use it when paths and relationships matter more than axes. The screenshot is captured from the native Fission chart gallery.

What the chart is for

Customer journey graph belongs to the Hierarchy family. Its job is to make this data shape readable: Relationship nodes and edges. In a production interface, choose this chart when the visual form makes the user's question faster to answer than a table or a simpler chart would.

Avoid it when the visual form makes the user estimate more than necessary; choose the simplest chart that answers the product question.

Data model

Relationship nodes and edges. Keep the data close to the Rust type that describes it. Fission Charts is typed Rust, so each chart uses explicit series and component structs instead of string configuration hidden in a loosely typed object.

Rust API

Field	Type	Notes
title	&str	Names the chart for the screen, accessibility tree, and test output.
series	Series	Provides the typed data model for this chart family.
width / height	f32	Optional fixed size; omit them when the chart should flex inside Fission layout.

Example

use fission_charts::{Axis, Chart, LineSeries};

let chart = Chart::new()
    .title("Trend")
    .x_axis(Axis::category(vec!["Mon", "Tue", "Wed", "Thu", "Fri"]))
    .y_axis(Axis::value())
    .series(vec![LineSeries::new("Revenue")
        .data(vec![120.0, 132.0, 101.0, 134.0, 190.0])
        .into()]);

Interaction and animation

Charts can emit typed ChartInteractionEvent values when interaction is enabled. Handle those events in a reducer when the app needs hover, press, release, scroll, selection, or brush behavior. ChartAnimation stores duration, delay, stagger, easing, and reduced-motion behavior as deterministic chart data, so animation timing can be tested instead of being hidden in ad-hoc timers.

Testing guidance

For this chart, test the data mapping first, then test lowering, then capture a live screenshot when visual output changes. The screenshot for this page is refreshed with npm run charts:generate from the website package.
