• Performance may degrade with large datasets or complex charts.

4. Plotly.js:

Plotly.js is a powerful JavaScript library for creating interactive, publication-quality graphs and dashboards. It provides a high-level API for creating a wide range of chart types, including scatter plots, line charts, bar charts, and heatmaps, as well as more advanced visualizations like 3D plots and contour plots. Plotly.js is highly customizable and supports interactivity features like hover tooltips, zooming, and panning, making it ideal for data exploration and analysis.

Pros:

• Supports a wide range of chart types and advanced visualizations.
• Highly customizable with support for interactivity features.
• Well-documented with extensive examples and tutorials.

Cons:

• Limited customization options for free users.
• Steeper learning curve compared to simpler libraries like Chart.js.
• Requires additional configuration and setup for complex visualizations.

5. Google Charts:

Google Charts is a free, easy-to-use JavaScript library for creating interactive charts and graphs using data from Google Sheets or external data sources. It offers a variety of chart types, including line charts, bar charts, pie charts, and geographic maps, with built-in support for customization options like colors, labels, and tooltips.
