<h2>D3.js "web site health check" - Treemap, shaded, from hierarchical JSON</h2>
<p>Source: Nathan Yau's <a href="http://flowingdata.com/2014/07/02/jobs-charted-by-state-and-salary/">"Jobs Charted by State and Salary."</a></p>
<p>Whole-ecology treemap visualization to surface quality problems in a large web site. Foundational data - content inventory plus traffic - can be paired with one or more new error reports of the moment, such as broken links. Helps product managers comprehend what their highest-severity problems are, and helps them decide what communication packages (thematic groups of pages) should be fixed first. Here, points are used instead of item counts, so management is able to shift work priorities by raising the severity of one or more error types. Production version includes a leaderboard.</p>
<p>The database this runs with has multiple error / fix reports, including:</p>
<ul>
<li>Broken links</li>
<li>Outdated video formats</li>
<li>Content not reviewed by a subject specialist in the past 12 months</li>
<li>Pages linking to Word, Excel, and other "non-web" documents that should be evaluated for conversion to HTML</li>
<li>Low percentage of task completion in customer survey</li>
<li>Low satisfaction in customer survey</li>
</ul>
<p>Create a sortable HTML table below as an accessible equivalent. Current colors are great for people who don't have color blindness; you may need to change the shading for your audience.</p>
