As a quick hack I have generated such a map for the UK. http://www.gedanken.org.uk/mapping/osm-junctions/junctions.html The junction data comes from Routino[1] and as such not all highway junctions are included (only highways that are routable). The rendering is performed client-side so is rather slow (probably my Javascript isn't optimum). The server will only allow downloading a limited amount of data at a time so I recommend you zoom in to the highest or penultimate zoom level.
