Deaths on Mt. Everest

Some graphs I put together of summits and deaths on Mt. Everest. These are very rough numbers, in part because of a lack of data about summit attempts and deaths after summiting.

The death rate is calculated as:

if summits == 0:
    if deaths == 0:
        rate = null
        rate = 1.0
    rate = deaths/(summits + deaths)
