I've been making progress with the Android version of the WineCompass mobile application and have implemented the major search features - by location, zip code, and state. Each establishment is display on a Google map with its marker corresponding to its category - winery, brewery, and distillery. The last major decision I need to make is how to show markers for populous states such as California, Oregon, and Washington. Should I just map each location as in Figure 1? Or is that too busy and instead, should I implement clusters, where clicking on a particularly cluster zooms the mapping coordinates to that location? See Figure 2. Once again I would appreciate your thoughts.
