* The chart library, with exactly the charts these figures draw registered.
*
* A module of its own so that the `import()` that fetches it can be *one*
* import of *one* chunk. Naming the pieces here, statically, is what lets the
* bundler drop the rest: ECharts is a large library and its `charts` and
* `components` entry points are barrels, so an `import('echarts/charts')` at
* the call site pulls in every chart type there is — gauges, maps, trees,
* sunbursts — none of which anything here draws. Measured, that mistake is
* about half a megabyte of the standalone build.
*
* `use` runs once, when the chunk is evaluated, which is exactly the semantics
* wanted: the registry is global to the library, and a second registration is
* either a no-op or a race.
