问题 In one application I have both d3 map and leaflet map, I follow Mike's code to sync them(http://bost.ocks.org/mike/leaflet/) and draw svg points on leaflet map.

I wonder if there's anyway to expand the SVG container based on the features (points) bound. a working demo is here: http://xqin1.github.io/usschools/usac_school
