Provide a default/generic URL that works and shows useful data for any nodeId e.g.

https://data.solarnetwork.net/generic?nodeId=183

If a node has too many data channels (e.g. > 10) this will be cumbersome on the UI, hence we need to control or limit the number of data channels shown. If we simply limit it to the first 7 data points that could still be really useful and hopefully very easy to implement.

As a V1 solution we don't need an all singing all dancing link, just a standard default/generic URL link that shows real data without knowing anything at all about the node (at the moment, the only way to get graphs out of a random node is to know a whole lot of hidden knowledge about that node). A first cut minimal viable product of this "Generic" URL would be a useful step forward.

e.g.
For node 111 (https://data.solarnetwork.net/solarquery/api/v1/pub/datum/mostRecent?nodeId=111), we would plot the following lines on a graph:

“val” line for source “/power/pcm/1”
“val” line for source “/switch/1”
“watts” line for source “East”
“wattHours” line for source “East"
“watts” line for source “West”
“wattHours” line for source “West”
