This example demonstrates how Ember’s component lifecycle manages the asynchronous spread of REST API data into a live-updating visualization. It shows data flowing from a server through Ember Data models, then being transformed and rendered as dynamic visual elements. The code uses `babel-plugin-transform-object-rest-spread` to enable modern object spread syntax within Ember CLI’s build pipeline, while the `.eslintrc` config enforces ES2017 parsing with experimental support for rest/spread properties. The rendering relies on Ember’s template and component system to bind incoming attributes to visual marks, though no specific charting library is visible. The approach focuses on state management and prop drilling rather than direct DOM manipulation, with data sourced from an unspecified Ember adapter.
