    # Create a figure
    p = figure(title="Scatter Plot with Colorbar", x_axis_label='X-axis', y_axis_label='Y-axis')

    # Add a scatter plot
    p.scatter('x', 'y', source=source, color='color', cmap=linear_cmap('color', low=min(data['color']), high=max(data['color'])))

    # Add a color bar
    color_bar = ColorBar(title="Color Scale")
    p.add_layout(color_bar, 'right')

    # Display the plot
    show(p)
