Are you working with a Feature Service or a Dynamic Map service layer? You will first need to create an event listener on the layer to determine if the user has clicked on the layer. Depending on the layer type, you must define the function for the layer click event - for Feature Layer you can use the geometry of the graphic feature directly and for Dynamic Services you probably need to do an Query or Identify Task (IdentifyTask | API Reference | ArcGIS API for JavaScript 3.18 ) first to retrieve the feature geometry. Then only can you use the map's setExtent function (Map | API Reference | ArcGIS API for JavaScript 3.18 ) to zoom to the extent of the portion

map.setExtent(esri.graphicsExtent([clickGraphic]))‍‍‍

So you want to draw a rectangle to select data and zoom to the selection or just zoom by rectangle?

Have you looked at the RubberBandZoom property of the map? Map | API Reference | ArcGIS API for JavaScript 3.18
