This is a incomplete list of resources on how to link react & d3. To my experience, there are as many approaches as there are (enter something numerous here). These approaches mostly differ as to 'who' has control over the dom and does the transitions etc. That distinction either requires the user to know more about react or d3, vice versa. Some of the approaches (like react-d3 or react-d3-components) include prebuilt charts, other just provide frameworks to place your charts in.
The following list tries to summarize some of the approaches, hopefully there will be some convergence to a (set of) standard(s), at one point.
This list is UNSORTED.
PLEASE let me know of any other links that should be included here ... or better yet, if there is such a list somewhere else :)

Nicolas Hery, let d3 do the charting work
##github sources/libraries d3act, motivated by Nicolas' approach, see above; this even ...has a youtube motivation
NEW: Victory, by Colin Megill of FormidableLabs again with video
react-d3, library including charts
d3-react-squared, a framework for reusable, linked charts
