geom_bar with large number of discrete values not showing bar plot

With a data frame df I have a large number of discrete values for metric and their counts cnt

I wanted to get a bar plot of the counts for each discrete value of metric.

So I do the following,

df <- read.csv("metric.csv", header=T)
df$metric <- as.factor(df$metric)
ggplot(df, aes(x=metric, y=cnt)) +
  geom_bar(stat = 'identity')

With the above I get an empty plot like below with this - why ?

The data I used for the data frame df is here - http://wikisend.com/download/569376/metric.csv

How do I get a bar plot out of this data ?

I'm not immediately aware of any limitations of geom_bar, but it is unsurprising that this doesn't work very well -- I interrupted it on my machine, so I don't even know what it looks like when it finishes rendering.

Are you sure that a bar plot is appropriate for this data? Which is to say, is the "metric" column effectively a factor?

Running a scatter plot completes rapidly with results that might be more useful (here using a log scale because a linear scale is hurt by the outlier)

ggplot(df, aes(x=metric, y=cnt) +
  geom_point() +
  scale_y_log10()

yields
