Power BI: Crafting Dynamic Animated Charts using Power BI and SQL Queries
DescriptionWelcome to our tutorial where we'll guide you through the process of creating an animated bar chart using Power BI and SQL queries. In this narrative journey, we'll harness the power of SQL Server database to display world population data on an engaging bar chart.
To begin, we'll leverage SQL queries to animate a normal bar chart in Power BI. Our goal is to showcase world population trends over the years, using data from a CSV file. This data spans from 1960 to 2022.
Our adventure commences by logging into our SQL Server and creating a new database. This clean slate becomes our canvas for importing the CSV file, which contains country names, years, and population data. To ensure smooth data integration, we meticulously verify data types and headers.
After importing, we fine-tune our tables, renaming and even duplicating them. The main table remains untouched, while the duplicate becomes a vessel for our animated chart. Using SQL commands, we explore the data, its insertion, and iteration, setting the stage for the animation process.
Taking a brief detour, we conjure a Power BI dashboard. Our vision unfolds as we add a title, a bar chart, and establish a connection to our SQL Server. This dashboard is our canvas, waiting for the vibrant data we're about to unveil.
The SQL loop beckons us. Guided by a variable "i," we traverse through years, creating a rhythmic pulse using a wait statement. With each beat, data flows from the main table into the duplicate, creating a mesmerizing animation.
Our dashboard plays its part seamlessly. The bar chart comes alive, populated with dynamic data. The backdrop of our journey is set as the year count evolves with each loop iteration. We take great care in refining our query, ensuring a clean slate for each cycle.
But our quest is far from over. We add a twist to our tale by introducing data deletion at the beginning, preventing any residual traces. The dashboard now embraces an additional card visual to display the current year, enhancing the interactive experience.
With each cycle, the card visual dances, synchronized with the animated bar chart. The dashboard is a symphony of data and visuals. Colors blend as the legend area springs to life, rendering our bar chart even more captivating.
Our journey culminates with a triumphant finale. The SQL query and dashboard unite in perfect harmony. The animated bar chart paints a vivid picture of world population growth over decades. A unique learning experience, bridging data science and visualization, has reached its zenith.
