There seems to be a few places where selectAll is being used where select is likely more appropriate.

Bubble Chart:
https://github.com/dc-js/dc.js/blob/develop/src/bubble-chart.js#L117
https://github.com/dc-js/dc.js/blob/develop/src/bubble-chart.js#L133

Bubble Mixin:
https://github.com/dc-js/dc.js/blob/develop/src/bubble-mixin.js#L133

Geo:
https://github.com/dc-js/dc.js/blob/develop/src/geo-choropleth-chart.js#L158

Heatmap:
https://github.com/dc-js/dc.js/blob/develop/src/heatmap.js#L234
https://github.com/dc-js/dc.js/blob/develop/src/heatmap.js#L237
https://github.com/dc-js/dc.js/blob/develop/src/heatmap.js#L252
https://github.com/dc-js/dc.js/blob/develop/src/heatmap.js#L269

Line:
https://github.com/dc-js/dc.js/blob/develop/src/line-chart.js#L356

Row:
https://github.com/dc-js/dc.js/blob/develop/src/row-chart.js#L208

Verify that all the heatmap and bubble chart/mixin ones are fixed by #1032 / #1237. Track down the rest of them, create failing tests, and verify fixes for them.
