A Lightning Web Component is a custom framework for creating reusable web components that run natively in browsers and leverage modern web standards. A custom ARC relationship graph is a metadata type in Financial Services Cloud that defines how account-account relationships are displayed in ARC, such as node shape, color, size, label, or icon. You can use Lightning Web Components and custom ARC relationship graphs to create customized nodes for ARC that show additional information or functionality for each account.
