This is my script for the plot,
data = data.frame(Kingdom = c("Bacteria", "Archaea"),
Total = c(273523, 2616))
sizeRange <- c(0,30)
library(ggplot2)
ggplot(data, aes(x=0,y=Kingdom,color=Kingdom)) +
geom_point(aes(size = Total,alpha=10),colour="blue",stroke=2) +
scale_size(range = sizeRange)+
theme_bw() +
theme(panel.border = element_blank(),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
axis.line = element_line(colour = "white"))
somebody, please tell me how can I get a connecting line between my y-axis label and the plot My plot looks like this

you can manually add segments, but then the alpha of your points will kind of show them.
Here is a try, altought it's not perfect if the x axis expend.
ggplot(data, aes(x=0,y=Kingdom,color=Kingdom)) +
# Added the segments here before the points.
# I tried to alpha it but I can't figure out how to limit the
# segment to the point border.
geom_segment(x = rep(-100,2), xend = rep(0,2),
y = c(1, 2), yend = c(1,2),colour="blue", alpha = 10) +
geom_point(aes(size = Total,alpha=10),colour="blue",stroke=2) +
scale_size(range = sizeRange)+
theme_bw() + guides(alpha = "none") + # remove alpha from legend.
theme(panel.border = element_blank(),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
axis.line = element_line(colour = "white"))

A clean alternative would be to label the points directly, and remove the y-axis if wanted. e.g.:
ggplot(data, aes(x=0,y=Kingdom,color=Kingdom)) +
ggrepel::geom_text_repel(aes(label = Kingdom), vjust = -1,colour="black") +
geom_point(aes(size = Total),colour="blue",stroke=2) +
scale_size(range = sizeRange)+
theme_bw() +
theme(panel.border = element_blank(),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
axis.line = element_line(colour = "white"),
axis.text.y=element_blank(),
axis.title.y = element_blank(),
axis.ticks.y=element_blank())
