Interface LaravelUi5\Core\Ui5\Contracts\Ui5ChartInterface

UI5 Chart — a single engine-tagged chart primitive rendered inside a {@see Ui5DashboardGroupInterface}, emitting a {@see \LaravelUi5\Core\Ui5\Controls\Lux\Chart} DTO. ECharts is the bundled engine at v0.9; the envelope shape ({engine, option}) leaves a clean entry point for v1.0+ engine pluralism.

Identity, title, description from {@see Ui5ArtifactInterface}; slot machinery from {@see SlottableInterface}.

Two seats, two jobs, no overlap (mirrors {@see Ui5TileInterface}):

• The Chart artifact is pure metadata (identity + slots) plus a handle to its provider. It is not a DTO factory — there is no static getChart() template on the artifact, because a chart's option tree is data-driven and only the executor has the data to build it.
• {@see ChartProviderInterface} is the executor that computes the whole engine-tagged DTO (engine + option) from the bound slot values and the request context at emit time.

The Chart's emitter ({@see \LaravelUi5\Core\Ui5\Dashboard\Emitters\ChartEmitter}) resolves the required slots, calls getChartProvider()->getChart($bound, $context), and returns the result verbatim.

Emitter selection is owned by the {@see \LaravelUi5\Core\Ui5\Dashboard\Contracts\DashboardTransformerInterface} via instanceof dispatch. See atom ARTIFACT_AS_DTO_FACTORY.md.
