The Bokeh server is an element of Bokeh. This is for making interactive web applications. Python code running on a server connects to it. The system mentions no-host values by default. 


Then, the Bokeh server will accept requests from the local host. The server is listening to (by default: 5006). Bokeh is a Python library. People use it to create interactive graphs and visualizations. You can do this in Bokeh using HTML and JavaScript. This is a powerful tool for custom charts and web design-based applications. The ColumnDataSource (CDS) is the core of Bokeh plots. It gives the data for the glyphs of the plot. When using lists or arrays to a Bokeh renderer, Bokeh creates a ColumnDataSource.   


The purpose of the Bokeh server is to create interactive Web applications. It can connect front-end UI events to real, running Python code. During the visualization, the Bokeh server gives convenient deploying HoloViews plots. This flexible and decoupled design gives some advantages. It is easy to work with other languages. Such as R or Scala, drive Bokeh plots and visualizations in the browser.   


The browser provides powerful capabilities:   

  • Respond to UI and tool events in the browser using the full power of Python.   
  • Push server-side updates to the UI elements (widgets or plots in the browser)   
  • use periodic, timeout, and asynchronous callbacks (streaming updates)   


Photographers use Bokeh. Their striking light effects highlight an element and blur the rest of the image. Bokeh, also called “Boke,” is one of the most popular advantages of photography. Bokeh makes photographs visually appealing. This focuses on a particular area of the image. The word comes from the Japanese language. It translates as “blur”.
