Mobile view of /energy/country page has charts that are too small to read

[mathisonian]

Description

There are some charts on e.g. https://ourworldindata.org/energy/country/united-states that are placed side-by-side when viewing on a mobile device.

Expected behaviour

The charts should be stacked vertically, rather than horizontally so that they are wide enough to see and read the chart.

Steps to reproduce

Steps to reproduce the behavior:

1. Go to https://ourworldindata.org/energy/country/united-states
2. Scroll down to 'What sources does the country get its energy from?'
3. See error
