Bokeh is a Python interactive data visualization. It renders its plots using HTML and JavaScript. It targets modern web browsers for presentation providing elegant, concise construction of novel graphics with high-performance interactivity. Bokeh can be used to plot line segments on a graph. Plotting line segments on a graph can be done using the Python3 
Example 2 : In this example we will be plotting the multiple line segments with various other parametersPython3 
segment() method of the plotting module.plotting.figure.segment()
Syntax : segment(parameters) Parameters :Example 1 : In this example we will be using the default values for plotting the graph.Returns : an object of class
- x0 : x-coordinates of the starting points of the line segment
- y0 : y-coordinates of the starting points of the line segment
- x1 : x-coordinates of the ending points of the line segment
- y1 : y-coordinates of the ending points of the line segment
