Aggregate data grouped by label - Your task is to fetch a list of conference rooms and label hierarchy and to display in a graph the total capacity of all conference rooms by label. 1. Fetch data You are given 2 API endpoints to use: getConferenceRooms Fetch a list of all conference rooms (no arguments) - returns a Promise that resolves into a list of conference room objects. Sample response: [ { "id": 1, "name": "Strawberry", "buildingName": "KennedyA", "labels": [4, 1], "capacity": 40, "hasProjector": true, "hasTv": true }, ... ] getLabels Fetch a list of all available labels (no arguments) - returns a Promise that resolves into a list of label objects. Sample response: [ { "id": 1, "name": "Large", "parentId": null }, ... ] 2. Calculate Total Capacity by Label Each conference room has a capacity: Number attribute and an optional list of labels?: Array representing IDs of the labels assigned to the room. Each Label has a name: String and an optional parentId: Number . Labels have hierarchy - A label is a child of another label if the other label has parentId that matches its id. Labels hierarchy is recursive - a label's descendants are its children, and all of their children recursively. Rooms are associated with a label if room.labels has the label or any of its descendants. The total capacity for a label is the sum of the capacity of all rooms associated with the label. 3. Display a Graph You are provided with a BarGraph component: Use it to display the graph of Total Capacity by Label as pictured above. 4. Filter the data You are provided with a Select component: Use it to select the labels to show in the graph. When no labels are selected show all labels in the graph.
