Because Relational pipes are a data format, it is bit difficult to spot them and capture their screenshot. Relational data look like this:
$ relpipe-in-cli generate some_relation 1 some_attribute string "some value" | hd
00000000 1d 0d 73 6f 6d 65 5f 72 65 6c 61 74 69 6f 6e 01 |..some_relation.|
00000010 0e 73 6f 6d 65 5f 61 74 74 72 69 62 75 74 65 03 |.some_attribute.|
00000020 1e 0a 73 6f 6d 65 20 76 61 6c 75 65 |..some value|
0000002c
But we can capture screenshots of some other formats and visual representations generated from the original relational data. There are some examples:
