Thanx for the effort. I see you've vertically aligned the names. It 
looks good, but I fear there has been a misunderstanding.

The ASCII diagrams were just to help me perfect the user-friendly file 
format I designed so both people preparing such files find them easy, 
and I find it easy to parse such files. Here again are the *.clad files:

Parent	Place	Node
root	above	Beetles
root	below	1
1		above	Wasps, bees, ants
1		below	2
2		above	Butterflies, moths
2		below	Flies

Parent	Place	Node
root	above	Archaeopterix lithographica
root	below	1
1		above	Apsaravis ukhaana
1		below	2
2		above	Gansus yumemensis
2		below	3
3		above	Ichthyornis dispar
3		below	4
4		above	5
4		below	6
5		above	Gallus gallus
5		below	Anas clypeata
6		above	Pasquiaornis
6		below	7
7		above	Enaliornis
7		below	8
8		above	Baptornis advenus
8		below	9
9		above	10
9		below	11
10		above	Brodavis varnei
10		below	Brodavis baileyi
11		above	Fumicollis hoffmani
11		below	12
12		above	Parahesperornis alexi
12		below	Hesperornis regalis

As for the JSON, I would never impose on my users the requirement of 
having to type in something like that. I do admit the JSON is easier to 
get right than YAML, but since we're talking about something a human has 
to type, my one-and-only concern is ease of use.

It's only after a program has parsed such data that the programmer can 
produce versions of the file in various formats.

And yes, I do use JSON, but only where I can call a library module (in 
Perl) from one of my CGI scripts (also in Perl, based on Mojolicious), 
to turn a data structure into JSON so when that data is sent to the web 
client (typically a browser [*]), the data structure can be easily 
decoded by Javascript.

[*] Just for the record, some web clients are not browsers. In fact 
millions of them are not browsers.

I have finished the parser, and almost finished the whole program. 
Progress is here:

Ignore the fuschia boxes. They are just inserted to make it easy for me 
to deal with the remaining problem of overlapping text.

As you can see, I've figured out how to shift the text when it overlaps, 
but I have not yet shifted the corresponding connecting lines. Hey! It's 
only 8:17 am here now. I'll update the images during the day.

And the scaffolding nodes, whose names are digits, will obviously be 
suppressed later.

The output you see is generated purely by default options within the 
program. There are almost a dozen options so far. All the user has to do 
is provide the *.clad files above. Simple!
