What is the method to extract numerous images from a bokeh html file as distinct png files, while also downloading them as a single zip file?

One possible method to extract numerous images from a Bokeh HTML file as distinct PNG files and download them as a single zip file is as follows:

1. Open the Bokeh HTML file in a web browser, such as Google Chrome or Firefox.
2. Right-click on the page and select "View Page Source" or use the keyboard shortcut Ctrl+U (Windows/Linux) or Command+Option+U (Mac) to open the page source code in a new tab.
3. Locate the section of the code that corresponds to the Bokeh plot, which typically starts with the tag
   and contains a JavaScript code block that initializes the Bokeh plot.
4. In the JavaScript code block, find the line that defines the Bokeh document, which usually starts with "Bokeh.safely(function(){" and ends with "});".
5. Inside the Bokeh document, there should be one or more Bokeh models that represent the images you want to extract. Each model typically has a unique name or ID, which can be found in the code.
6. Use JavaScript code to extract the data URLs of the images, which are typically stored as attributes of the Bokeh models. The data URL should start with "data:image/png;base64," followed by a long string of characters that represents the encoded PNG data.
7. Use JavaScript code to create a new <canvas> element for each image and draw the image data onto the canvas using the canvas's 2D context.
8. Use JavaScript code to convert the canvas element to a PNG image data URL using the canvas's toDataURL() method.
9. Create a new element with a unique filename and the PNG data URL as its href attribute.
10. Use JavaScript code to simulate a click event on the element to download the PNG file to the user's computer.
11. Repeat steps 7-10 for each image you want to extract, using a unique filename and data URL for each image.
12. Use a JavaScript library such as JSZip to create a new zip archive and add each PNG file to it.
13. Create a new element with a filename like "images.zip" and the zip file data URL as its href attribute.
14. Use JavaScript code to simulate a click event on the element to download the zip file to the user's computer.
