How to plot a graph in R using CSV file ?

To plot a graph in R using a CSV file, we need a CSV file with two-column, the values in the first column will be considered as the points at the x-axis and the values in the second column will be considered as the points at the y-axis. In this article, we will be looking at the way to plot a graph using a CSV file in R language.

**Approach**

- Import csv file
- Pass required parameters to plot function
- Plot graph
- Display plot

**Functions Used:**

- To import/read the CSV file to the R console, the user must need to use the read.csv() function in R.This function will read a CSV file available in your current working directory.

**Syntax:**

read.csv(file)

- plot() function for plotting of R objects. With the provided parameters this function returns a scatter plot by default.

Syntax:plot(x,y,main,xlab,ylab,sub,asp)

Parameters:

- x:-the x coordinates of points in the plot
- y:-the y coordinates of points in the plot
- main:-an overall title for the plot
- sub:-a subtitle for the plot
- xlab:-a title for the x-axis
- ylab:-a title for the y-axis
- asp:-the y/x aspect ratio

Return:Scatter plot of the given x and y values.

**Example:**

## R

`data=` `read.csv` `(` `'input_gfg.csv'` `)` ` ` `print` `(data)` ` ` `plot` `(x = data$x,y = data$y,` ` ` `xlab = ` `"x-axis"` `,` ` ` `ylab = ` `"y-axis"` `,` ` ` `main = ` `"Plot"` `)` |

**Output:**
