+This module provides a utility class for counting and reporting frames per second (FPS) in a PyQtGraph application.
+
+Classes:
+    FPSCounter: A class that monitors the paint events of a `ViewBox` to calculate and emit FPS values.
+
+Usage:
+    The `FPSCounter` class can be used to monitor the rendering performance of a `ViewBox` in a PyQtGraph application.
+    It connects to the `ViewBox`'s paint event and calculates the FPS over a specified interval, emitting the FPS value
+    at regular intervals.
+
+Example:
+    from qtpy import QtWidgets, QtCore
+    import pyqtgraph as pg
+    from fps_counter import FPSCounter
+
+    app = pg.mkQApp("FPS Counter Example")
+    win = pg.GraphicsLayoutWidget()
+    win.show()
+
+    vb = pg.ViewBox()
+    plot_item = pg.PlotItem(viewBox=vb)
+    win.addItem(plot_item)
+
+    fps_counter = FPSCounter(vb)
