Need to add more methods and resources specific to data viz design, not just general UX design

[jessielian]

There isn't much that's unique to designing for dashboards-- like how do we diverge in different data visualizations, how do we organize & design them to answer users' questions, how do we evaluate which viz is best (we can probably reference evaluation toolkit here), how do we know our viz actually works with the real data (can also reference the design+data model framework)
