Chart.js is a widely used open-source JavaScript library designed for creating visually appealing, interactive charts directly in the browser. Its main purpose is to simplify the process of turning raw data into clear, engaging visualizations that help users understand trends, patterns, and comparisons. Chart.js is especially popular in web development because it allows you to add charts to web pages with minimal effort, using just a few lines of code. You can use Chart.js to display data in various formats, such as line charts, bar charts, pie charts, and more, making it a flexible solution for dashboards, reports, analytics tools, and any application that benefits from data visualization.

Chart.js stands out due to its ease of use, responsive design, and smooth animations. It integrates seamlessly with modern web technologies and works well with frameworks or vanilla JavaScript. Common use cases include:

• Displaying sales data trends;
• Visualizing survey results;
• Monitoring website analytics;
• Presenting any information that is easier to interpret visually rather than in raw numbers or tables.
