How can I implement multithreading in a Qt application for data visualization?

You can use QThread to manage threads in Qt. Start by subclassing QThread and implementing the run() method for your data processing.

What about updating the UI from a worker thread?

You should use signals and slots to safely update the UI from a worker thread. Emit a signal from your worker thread and connect it to a slot in your main thread.

Can you give an example of how to emit a signal?

Sure! In your worker class, you can define a signal like this: signals: void dataReady(const DataType &data); Then emit it using emit dataReady(processedData);.

How do I handle thread termination gracefully?

You can call requestInterruption() in your worker thread and check for it in your run() method to terminate the thread safely.
