Eh, I&#x27;m a snob, I know, but I think the UX for both this and the 404 page is poor.<p>For the dataviz, I noticed many nits, but for brevity I&#x27;ll say this:, I think the visualization falls way short of communicating patterns in the data, or indeed illustrating any relative significance of a given match set over others.  The design and the narrative need some work.  I can see the gender matches are illustrated, but it isn&#x27;t communicated why that is important.  The D3 development work is adequate, but within that, there are some behaviors that could use some tweaks finesse (for example on desktop, when hovering across multiple items to a specific, the experience stalls slightly while calculating the graph updates for each item).<p>The 404 page shows some personality for sure, so that&#x27;s cool, but a 1.6meg choppy animated gif isn&#x27;t exactly awesome, and the repeat-x doesn&#x27;t add anything either.
