Applying easy-model in Data Visualization Dashboards

Data visualization dashboards need to handle large amounts of data, chart configurations, user interactions, and other complex logic. easy-model's model-driven architecture can effectively organize these features, improving development efficiency. This article demonstrates easy-model's advantages in dashboard development through real examples. Chart Configuration Model Charts are the core of dashboards. We create ChartModel to encapsulate chart logic: import { useModel } from " @e7w/easy-model " class ChartModel { config = { type : " bar " as " bar " | " line " | " pie " , data : [] as Array < { label : string ; value : number } > , title : "" , showLegend : true }; constructor ( initialConfig : typeof this . config ) { this . config = initialConfig ; } updateData ( newData : typeof this . config . data ) { this . config . data = newData ; } toggleLegend () { this . config . showLegend = ! this . config . showLegend ; } getMaxValue () { return Math . max (... this . config . data . map
