Python Bokeh is one of the best Python packages for data visualization. Today, we are going to see some Python Bokeh Examples. I have also provided the Python Bokeh project source code on GitHub. Learn this easy visualization tool and add it to your Python stack.
Python Bokeh is a data visualization tool, or we can also say Python Bokeh is used to plot various types of graphs. There are various other graph plotting libraries like matplotlib, but Python Bokeh graphs are dynamic in nature, which means you can interact with the generated graph. See the below examples…
Python Bokeh can be easily installed using PIP. You can install the Python Bokeh easily by running the command:
pip install bokeh
Now everything is ready, let’s go through the examples 🏃♂️…
