Here is a simplified version of the HTML code with comments explaining what each section does:
```html
<!-- Figure container -->
<figure id="gv-atom-uk-news-ownership-graph" data-did-prerender="true">
<!-- Grid container for the news ownership graph -->
<div class="grid svelte-98k19t">
<!-- Section containers for the graph layout -->
<div class="section svelte-98k19t">
<!-- Container for the graph content, but currently empty -->
<div class="container svelte-eqg328"><div></div></div>
</div>
<!-- Repeat this section pattern 6 times -->
<div class="section svelte-98k19t">
<div class="container svelte-eqg328"><div></div></div>
</div>
<div class="section svelte-98k19t">
<div class="container svelte-eqg328"><div></div></div>
</div>
<div class="section svelte-98k19t">
<div class="container svelte-eqg328"><div></div></div>
</div>
<div class="section svelte-98k19t">
<div class="container svelte-eqg328"><div></div></div>
</div>
<div class="section svelte-98k19t">
<div class="container svelte-eqg328"><div></div></div>
</div>
</div>
</figure>
```
This code uses a repetitive pattern to create the layout of the news ownership graph, with each section containing an empty container. The `@font-face` rules define the fonts used for the graph's text content, while the `svelte-eqg328` and `svelte-98k19t` classes are likely styles defined by a CSS file imported into the HTML document.
Note that this is just one possible interpretation of the code, and there may be other ways to simplify or reorganize it depending on the specific requirements of the project.
