    • To modify the curve, simply click and drag the data points using your mouse to reposition them as needed.
    • To modify the axes, simply click and drag a data point (for example, the one indicating the turning point) beyond the edge of the graph. Upon releasing the data point, the axes will automatically recalibrate to reflect the new position.
