Visualization
The following are the parameters I used for the sales data visualization;
- Sales Over Time
- Top Products by Sales
- Sales by Region
Sales Over time
In this study, I use a line chart to visualize sales over time between January 2003 and April 2005 based on the Sales Sample Data. The ORDERDATE column was converted to the datetime data format. Find image below.
The line chart above shows total sales over time (2003 - 2005). The x-axis represents the date (by month), and the y-axis represents the total sales for each month. This visualization helps identify trends and patterns in sales over a given period.
Top Products by Sales
I used bar chart to visualize top products by sales. First, I aggregated the PRODUCTLINE column. Find image below.
From the above image, find the percentage of sales below by percentage.
- Motorcycles; 11.7%
- Classic Cars; 34.3%
- Trucks and Buses; 10.7%
- Vintage Cars; 21.5%
- Planes; 10.8%
- Ships; 8.3%
- Trains; 2.7%
From the above statistics, the top 3 highest Products by sales are Classic Cars (34.3%), Vintage Cars (21.5%), and Motorcycles with a staggering 11.7%.
Sales by Region
In order to visualize top sales by region, I aggregated the COUNTRY column using a pie chart. Find image below;
The above visualization shows the top 3 sales by region with US topping the chart with 35.6%, followed by Spain with 12.1% and France with 11.1%.
