# Facet Layout at Scale (Network example)

> WestCoast Charts 1.1.5, release, public Core release, on npm. HTML: https://westcoast-charts.com/gallery/network/facet-estate/ · Index for agents: https://westcoast-charts.com/llms.txt

Eight business domains, 640 services: crowded shells stagger into rows, cross-domain traffic folds into one ribbon per domain pair (Payments – Commerce carries most of it), and two causal chains stay legible on top. Hover a node to light its facet and paths.

## Question

Where do services belong, and which dependencies cross business domains?

## How to read it

- Facets: Eight business domains group the 640 services.
- Shells: Core, domains, teams and services preserve the hierarchy.
- Paths: Highlighted chains remain distinct from the bundled background connections.

Try: Hover a node to highlight its facet and paths, then zoom to inspect individual services. Use the domain overview for orientation before following one chain.

## Setup

```js
import WestCoastCharts from 'west-coast-charts'
import types from 'west-coast-charts/types'
import premium from 'west-coast-charts/premium'
import networkFacet from 'west-coast-charts/layers/network-facet'

WestCoastCharts.use(types).use(premium).use(networkFacet)
const WestCoastChartsPremium = premium
const WestCoastChartsLayer_networkFacet = networkFacet
WestCoastCharts.setLicenseKey(LICENCE_KEY) // paid production licence; localhost evaluation needs no key
```

## Options

This example builds its charts with page controls and helpers, so there is no single options object. Read the standalone example for the source.

## Verify

- Text check (Library 1.1.5): load `west-coast-charts/agent/describe` and call `chart.describe({ format: "json" })` for the actual drawn state. The live reader is on this example’s HTML page.
- Command line (Public agent tools 0.2.3, tested with Library 1.1.5; available from the versioned GitHub release and npm, https://westcoast-charts.com/docs/cli/index.md): `wcc chart export network-facet-estate.json --out network-facet-estate.svg --with-table` (save the options above as JSON first)
