Like _doug9forester_, I have a project for which this style of diagram seems ideal, and have encountered the same trouble with captions not fitting within containers. I feel there should (or even must) be some parameter which sets limits to the "ballooning", as I notice that the containers are shrunk to fit any very short captions.
I'm also wondering how to specify a rectangular shape for some of the bubbles.
Exploring the code, I've worked out how to specify the _-data_ file on the command line, and
also how to hand-code the diagrams in this file. Details are below, in the hope that someone may find this information helpful.
At the top of the file _bubble-generator.tcl_, Instead of
```
set datafile [file join [file dirname [info script]] bubble-generator-data.tcl]
source $datafile
```
I've put the following
```
if {$argc == 0} {
set datafile [file join [file dirname [info script]] bubble-generator-data.tcl]
} else {
set datafile [lindex $argv 0]
}
source $datafile
```
And my data file currently looks like what appears below.
```
# Graphs:
#
set all_graphs {
ipv4-resolution {
line /hostname
{or
nil
{line {toploop
{or
CNAME
DNAME
}}}} A /ipv4-address-set
}
ipv6-resolution {
line /hostname
{or
nil
{line {loop
{or
CNAME
DNAME
}}}} AAAA /ipv6-address-set
}
}
```
