The finance manager sends the financial chart to all participants, and it is displayed next to the sales manager's video. The application sends the audio and a video of the new speaker to the other participants. In the background, the finance manager uses the data from the shared spreadsheet, requests the holiday sales from a local database, and merges the appropriate figures into a shared graphics application. The other participants can watch the finance manager make the corrections through the shared application without any performance impact to the application. The finance manager sends the updated chart to all participants.
