There is a logical inconsistency it would seem. The svg title is more a
property of the plot than of the terminal.

Correct me if I am wrong but I suppose all the features we are
discussing here are established in stable releases and hence pose a
problem of backwards compatibility if they are changed. Specifically ,
does that apply to the 'name' option?


I see on your demo titles of the following form:

<g id="simple_3_plot_1" ><title>simple_3_plot_1</title>

could you explain how that is created or post a link to the scripts that
make it?
