ride-hail-trips.payment_type: 3 values, 100.0% in the top three

Distribution of payment_type on ride-hail-trips, because every chart built on it inherits this shape.

• card — 4,983 rows, 62.3%
• wallet — 2,125 rows, 26.6%
• cash — 892 rows, 11.2%

The top three take 100.0% between them. With only 3 values there is no tail to worry about, which makes this a genuinely easy column to chart.

select payment_type,
       count(*)                                      as rows,
       round(100.0 * count(*) / sum(count(*)) over (), 1) as pct,
       round(avg(fare_usd)::numeric, 2)             as avg_fare_usd
from ride_hail_trips
group by 1
order by rows desc;

The second column is the one that matters. Share of rows tells you what is common; avg_fare_usd tells you whether the common thing is the important thing. They disagree more often than not, and a chart that shows only the first is answering the easier question.

Decide what happens to the tail before you plot it. "Other" as an explicit bucket is honest; twelve slivers is not, and neither is silently taking the top eight.
