This shows how separate charts can be enclosed in d3.dispatch events, and based on generic update events, we can trigger each chart to update accordingly. Crossfilter .filter() takes care of updating the dimensions groups so we simply need to re-trigger part of the chart's code that updates the chart with new data.
