What is missing
How many records lack each field, emptiest first. A field counts as missing when it is null or empty, so a column of blanks is never reported as complete. An empty field is an outstanding gap, not an error: nobody has established that value for that record yet.
What there is to show
How many records carry each kind of visual, emptiest first. Field coverage cannot answer this: the line drawing is a column on the record, but photographs, renders, 3D models and schematics are rows in tables of their own. Two counts, because they are different facts — records is how many firearms have at least one asset of that kind, assets is how many files exist, and the second is larger wherever a record carries several. The kinds do not add up to the catalog: a record with a drawing and a photograph appears in both rows, which is what the final row is for.
