Add count as label to points in geom_count

This might help you I used geom_count to visualise overlaying points as sized groups, but I also want to add the actual count as a label to the plotted points, like this: , Are you expecting this:
ggplot(data %>% 
         group_by(id) %>%
         summarise(x = mean(x), y = mean(y), count = n()), 
       aes(x = x, y = y)) + geom_point(aes(size = count)) +
  scale_size_continuous(range = c(10, 15)) +
  geom_text(aes(label = count),
            color = "#ffffff")
p <- ggplot(data = data, aes(x = x, y = y)) +
  geom_count() + scale_size_continuous(range = c(10, 15))
p + geom_text(data = ggplot_build(p)$data[[1]], 
              aes(x, y, label = n), color = "#ffffff")

Color points by their occurrence count in ggplot2 geom_count

will be helpful for those in need You can color points by their occurance with color = ..n.. in aes. See the follow example:
ggplot(mtcars, aes(cyl, carb)) + geom_count(aes(color = ..n..))
ggplot(mtcars, aes(cyl, carb)) +
    geom_count(aes(color = ..n.., size = ..n..)) +
    guides(color = 'legend')

R ggplot2 ggrepel - label a subset of points while being aware of all points

I hope this helps . You can try the following:
Assign a blank label ("") to all the other points from the original data, so that geom_text_repel takes them into consideration when repelling labels from one another; Increase the box.padding parameter from the default 0.25 to some larger value, for greater distance between labels; Increase the x and y-axis limits, to give the labels more space at the four sides to repel towards.
ggplot(dt, 
       aes(x = one, y = two, color = diff_cat)) +
  geom_point() +
  geom_text_repel(data = . %>% 
                    mutate(label = ifelse(diff_cat %in% c("type_1", "type_2") & abs(diff) > 2,
                                          name, "")),
                  aes(label = label), 
                  box.padding = 1,
                  show.legend = FALSE) + #this removes the 'a' from the legend
  coord_cartesian(xlim = c(-5, 5), ylim = c(-5, 5)) +
  theme_bw()

How to label points in a large scatterplot (~280k points)

fixed the issue. Will look into that further I was able to plot everything nicely with plotly like this, using plotly's Scattergl to speed everything up.
import plotly as plotly
py = plotly.offline
import plotly.graph_objs as go

trace = go.Scattergl(
    x = points['x'], 
    y = points['y'],
    text = points['word'], 
    mode = 'markers',
    marker = dict(
        color = '#FFBAD2',
        line = dict(width = 1)
    )
)

data = [trace]
layout = plotly.graph_objs.Layout(hovermode='closest')
figure = plotly.graph_objs.Figure(data=data, layout=layout)
py.plot(figure)

Can I plot the number count in ggplot2 using geom_text instead the size of points (geom_count)?

it should still fix some issue Take a look at this example:
Add count as label to points in geom_count
p <- ggplot(data = Data,aes(CIM,DD)) +
  geom_count(show.legend = FALSE)+
  scale_x_continuous(limits = c(1, 32), breaks = breaks, labels = labels,name = "CIM") +
  scale_y_continuous(limits = c(1, 32), breaks = breaks, labels = labels,name = "DD") +
  scale_size_continuous(range = c(10, 10))

p + geom_text(data = ggplot_build(p)$data[[1]], aes(x, y, label = n), color = "#ffffff")
