Bar and Column Charts

Let's dig into some different types of charts! Starting of course, with Bar Charts.

A Bar Chart displays data using horizontal bars. Each bar represents a category, and the length of the bar represents its value. Here's an example from a different data set:

What Are Bar Charts Good For?

Comparing total values between categories (e.g., Sales by Region, Revenue by Product Category)
Highlighting differences across groups
Showing rankings or proportions

Bar and column charts are great when you have a category (like region or product category) on one axis and a numeric value (like sale_quantity) on the other axis.

Vertical vs. Horizontal

A column chart is just a bar chart with vertical bars instead of horizontal ones... hopefully that's obvious.

I prefer bar charts (horizontal) when I have long category names or many items to compare. I prefer column charts (vertical) when I have fewer categories and want to emphasize height rather than length.

Assignment

Click the "+" sign at the bottom of the page on the Report view to open a new page (page 2).
Rename Page 1 to "Customers". Rename Page 2 to "Sessions". You can rename a page by double-clicking its tab at the bottom of the screen.
In the Visualizations Pane on the right, click the Clustered Column Chart icon to add a new chart.
Resize the chart to take up the top half of the canvas. Notice that you can "snap" the bottom of the chart to the halfway point.
From the website_sessions data in the Data pane, drag device_type to the X-axis and session_pages_visited to the Y-axis.
Title the new chart "Pages Visited by Device".

Save the project and, from the course directory, submit the CLI tests.
