Use google bigquery to build histogram graph

Question

How can write a query that makes histogram graph rendering easier?

For example, we have 100 million people with ages, we want to draw the histogram/buckets for age 0

Answer 1

You could also use the quantiles aggregation operator to get a quick look at the distribution of ages.

SELECT
  quantiles(age, 10)
FROM mytable

Each row of this query would correspond to the age at that point in the list of ages. The first result is the age 1/10ths of the way through the sorted list of ages, the second is the age 2/10ths through, 3/10ths, etc.
