Introduction to ggplot2
ggplot2 is part of the tidyverse collection of R packages. It's used to create powerful, layered, and customizable data visualizations.
To use it, load the libraries:
library(tidyverse)
library(ggplot2)
Disable scientific notation to make plots more readable:
options(scipen = 999)
Read the dataset:
df <- read_csv("car_details.csv")
View(df)
Basic Structure of a ggplot2 Plot
Every ggplot2 visualization is constructed in layers:
ggplot(data, aes(x, y)) + geom_function()
-
data: the dataset being used. -
aes(): aesthetic mapping (e.g., x and y axes). -
geom_*(): geometry layer that decides how the data should appear (e.g., bars, points, lines).
