Represent the following data by a bar graph:

Name of student	Kavya	Ariv	Ahaan	Arya	Arushi
Marks scored	$90$	$80$	$50$	$60$	$40$

(N/A) To represent the data using a bar graph,follow these steps:
$1$. Draw two perpendicular axes: the horizontal axis ($x$-axis) and the vertical axis ($y$-axis).
$2$. Along the $x$-axis,mark the names of the students (Kavya,Ariv,Ahaan,Arya,Arushi) at equal intervals.
$3$. Along the $y$-axis,choose a suitable scale to represent the marks scored. For example,$1 \text{ unit} = 10 \text{ marks}$.
$4$. Draw bars of equal width for each student,with heights corresponding to their respective marks:
- Kavya: $90$
- Ariv: $80$
- Ahaan: $50$
- Arya: $60$
- Arushi: $40$
$5$. Ensure there is equal spacing between the bars.
