This is a complex HTML document, and I'll do my best to provide a concise answer.
**HTML Structure**
The HTML structure consists of:
1. `<figure>`: The outermost container.
2. `<div class="interactive-wrapper">`: A wrapper for the interactive content.
3. `<div class="gv-wrapper">`: Contains the Guardian-specific elements.
4. `<div class="gv-header-background">`: Header background element.
5. `<div id="gv-header" class="gv-header">`: The header section with title and navigation links.
6. `<div id="gv-list-view" class="gv-list-view close">`: A list view container that will contain the data grid or a scrollable list.
7. `<div id="gv-grid-view" class="gv-grid-view open">`: A grid view container that will display the list data in a table format.
8. `<div class="gv-footer">`: The footer section with photo credit information.
**Code Changes**
To make the code more concise, I would suggest:
1. Removing unnecessary comments and empty lines.
2. Combining similar elements (e.g., multiple `div` containers can be merged into a single one).
3. Using shorter class names where possible.
4. Eliminating redundant attributes or properties.
Here's an updated version of the HTML code with some suggested changes:
```html
<figure>
<div class="interactive-wrapper">
<div class="gv-wrapper">
<!-- Header -->
<div class="gv-header-background">
<div id="gv-header" class="gv-header">
<span class="gv-strap">Football</span>
<h1>Next Generation 2017: 60 of the best young talents in world football</h1>
<p class="gv-standfirst"></p>
<!-- Navigation links -->
</div>
</div>
<!-- List View -->
<div id="gv-list-view" class="gv-list-view close">
<!-- Data grid or scrollable list will be inserted here -->
</div>
<!-- Grid View -->
<div id="gv-grid-view" class="gv-grid-view open">
<div class="gv-grid" id="gv-grid">
<!-- Data table will be inserted here -->
</div>
</div>
<!-- Footer -->
<div class="gv-footer">
<div id="gv-footer-photo-credit" class="gv-footer-photo-credit">Photographs: ...</div>
</div>
</div>
</div>
</figure>
```
Please note that this is just a suggestion, and the actual code may require more changes to achieve the desired structure and functionality.
