Create examples for core linked view patterns

[curran]

Chiasm should readily support the following linked view patterns, and have examples for each:

• [X] Focus + Context via brushing - 1D, 2D
• [ ] Interactive time slicing - Line chart + Bar chart example, Line Chart + Choropleth example
• [X] Multidimensional filtering via brushing & picking - replicating Crossfilter example and DC.js example
• [ ] Linked brushing with global selection - replicating Scatterplot Matrix Brushing but for multiple different visualizations (e.g. Parallel Coordinates)
• [ ] Linked hovering with globally highlighted row. Similar to interaction in Multi-line Voronoi example and Voronoi-based point picker.
• [ ] Tooltips that follow the mouse, depending on voronoi overlay
