Bokeh Line Plot with Random Data

This function generates a line plot with random data using the Bokeh library. It first generates random X and Y values, then creates a ColumnDataSource to store these data. Next, it creates a new plot with a title and axis labels, and adds a line plot with a diamond marker. Finally, it saves the plot as an HTML file.
