ds %>%
  ggplot(aes(x=location, y=temp_3pm, fill=location)) +
  stat_summary(fun="mean", geom="bar") +
  labs(x=vnames["location"],
       y=glue('Mean {vnames["temp_3pm"]}')) +

When a bar chart has many bars and non-trivial labels then it is useful to rotate the labels. Here we plot the mean temperature at 3pm for each location in the dataset. Without rotating the x-axis labels (the locations) the x-axis will be blighted with much overlapping. Labels can be rotated using a ggplot2::theme() option of axis.text.x= with angle=$45^\circ$. Use hjust=1 to align the labels appropriately.
