Make an Circle Glyphs in Python using Bokeh

Last Updated : 15 Jul, 2025

is a

interactive data visualization. Unlike

and

, Bokeh 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.

Different shapes such as circle, rectangle, polygon, etc. can, be drawn by the figure object. Bokeh Figure class following methods to draw circle glyphs which are given below:

• circle()
• circle_cross()
• circle_x()

circle() method is a used to add a circle glyph to the figure and needs x and y coordinates of its center.

Syntax: circle(x, y, *, angle=0.0, angle_units=’rad’, fill_alpha=1.0, fill_color=’gray’, line_alpha=1.0, line_cap=’butt’, line_color=’black’, line_dash=[], line_dash_offset=0, line_join=’bevel’, line_width=1, name=None, radius=None, radius_dimension=’x’, radius_units=’data’, size=4, tags=[], **kwargs) Parameter:This method accept the following parameters that are described below:

• x: This parameter is the x-coordinates for the center of the markers.
• y: This parameter is the y-coordinates for the center of the markers.
• angle: This parameter is the angles to rotate the markers.
• fill_alpha: This parameter is the fill alpha values for the markers.
• fill_color: This parameter is the fill color values for the markers.
• radius: This parameter is the radius values for circle markers .
• radius_dimension: This parameter is the dimension to measure circle radii along.
• size: This parameter is the size (diameter) values for the markers in screen space units.

# Implementation of bokeh function 
   
import numpy as np  
from bokeh.plotting import figure, output_file, show 
   
plot = figure(plot_width = 300, plot_height = 300) 
plot.circle(x = [1, 2, 3], y = [3, 7, 5],  
            size = 20, color ="green", alpha = 0.6) 
   
show(plot) 

circle_cross() method is a used to add a circle glyph with a ‘+’ cross through the center to the figure and needs x and y coordinates of its center.

Syntax: circle_cross(x, y, size=4, angle=0.0, *, angle_units=’rad’, fill_alpha=1.0, fill_color=’gray’, line_alpha=1.0, line_cap=’butt’, line_color=’black’, line_dash=[], line_dash_offset=0, line_join=’bevel’, line_width=1, name=None, tags=[], **kwargs) Parameter:This method accept the following parameters that are described below:

• x: This parameter is the x-coordinates for the center of the markers.
• y: This parameter is the y-coordinates for the center of the markers.
• angle: This parameter is the angles to rotate the markers.
• fill_alpha: This parameter is the fill alpha values for the markers.
• fill_color: This parameter is the fill color values for the markers.
• radius: This parameter is the radius values for circle markers .
• radius_dimension: This parameter is the dimension to measure circle radii along.
• size: This parameter is the size (diameter) values for the markers in screen space units.

show(plot) 

circle_x() method is a used to add a circle glyph with a ‘X’ cross through the center. to the figure and needs x and y coordinates of its center.

Syntax: circle_x(x, y, size=4, angle=0.0, *, angle_units=’rad’, fill_alpha=1.0, fill_color=’gray’, line_alpha=1.0, line_cap=’butt’, line_color=’black’, line_dash=[], line_dash_offset=0, line_join=’bevel’, line_width=1, name=None, tags=[], **kwargs) Parameter:This method accept the following parameters that are described below:
