Explanation

This HTML code defines a dashboard for visualizing comparison results from the Splink library. It mainly focuses on displaying a comparison table, allowing users to interact with various controls to customize the view. Here’s a breakdown of the code:

Structure:

<head>:

Defines the title and meta description for the webpage.
Includes CSS styles to format the page, including table styles, controls styling, and typography.
Imports the “Source Sans Pro” font from Google Fonts for consistent text rendering.

<body>:

Embeds a script using a Self-Executing Anonymous Function (SEAF) to load the comparison viewer.
