Before making any changes in a work session, a developer must save both the content data and the display code.
Saving only one part can lead to problems.
A developer works with two main parts: the content and how it looks. The content is often stored as data, like JSON. The display code is often HTML. These two parts work together. If a developer only saves one part, the other part might not match. This can cause errors or lost work.
A developer wants to change text on a webpage. The text is in a JSON file. The webpage layout is in an HTML file. The developer only backs up the JSON file. Later, the developer makes a mistake in the HTML file. The developer cannot restore the HTML file to its previous state. The webpage looks broken.

A developer creates a new HTML file for the chart. This file contains all the chart's features.
A developer uses `#interactive-svg-demo` for the main section that holds an SVG image. JavaScript code will interact with this section.
A developer might use `innerHTML` to update a part of a web page. This method replaces all content inside a specific area.
