You will learn: how to use the Map Viewer to style layers and create meaningful visualizations.
The ArcGIS Online Map Viewer can be used to style web maps and create powerful visualizations for your applications. The Map Viewer allows you to easily change the basemap and style individual layers in the map. The viewer provides styling suggestions (smart mapping) when layers are loaded, but you can also change symbols, colors, and shapes interactively with styling tools. Layers can also be styled (classified) by attribute values with different symbols. Another type of styling is formatting a layer pop-up. Styling layers with the Map Viewer is the fastest way to update a mapping application without changing your code because all changes are stored in the web map and are immediately reflected in applications that use them. You can learn how to load a web map in your application in the Display a web map lab.
In this lab, you'll use the Map Viewer to style the Trailheads, Trails, and Parks and Open Space layers to create a more meaningful map.

Local Park: Light Purple
Natural Areas: Light Green
Regional Open Space: Light Blue
Reginal Recreation Park: Light Red
