I don't understand this. The co2_growth_prct is shown as ,, for 1952, even though it must be 0, according to the co2 value for 1951 and 1952. same happens for 1953 to 1954. I would expect empty values ,, to mean NULL or unknown, but not 0 (zero).

Possible related to #16 — at least the data already looks like this in our grapher dataset, so the issue is further upstream.
