How many mills of 'Grondzeiler' type are built in each year? Give me the trend, list in descending by the X-axis.
SELECT built_year, COUNT(built_year) FROM mill WHERE type = 'Grondzeiler' ORDER BY built_year DESC
SELECT "built_year", COUNT("built_year") FROM "mill" WHERE "type" = 'Grondzeiler' ORDER BY "built_year" DESC
