After starting the demo pvserver you may start pvbrowser.
Linux:
pvbrowser
Windows:
.\pvb\win-mingw\bin\pvbrowser.exe
pvbrowser will connect to it's default pvserver at localhost. Within the window you see a simple demo visualization. The demo is mainly a periodic table of the available widgets. Please experiment around a little. Also look to “File->Options”. Here you can customize pvbrowser. Note that some changes under Options only take effect after restarting pvbrowser.
