This example demonstrates a live sensor-data visualization using the Firmata library to communicate with an Arduino board over a serial connection. The code establishes a board connection via `firmata.Board` and logs a message once the link is ready, though it does not yet render any visual output. The focus is on the initial data-acquisition stage, where raw input from the board would be captured and prepared for future graphical mapping. The visualization’s rendering approach remains unspecified, as the current code only handles the communication handshake.
