5 Best Data Visualization Tools by Webix

In today’s world, where insights need to be fast, interactive, and user-friendly, developers and analysts turn to data visualization tools that deliver meaningful, real-time data in visually intuitive formats. Looking for an easy way to visualize data effortlessly and with high performance? Check out these 5 best data visualization tools that are available in Webix JavaScript components.They are designed to help you build clear, informative visualizations and analytics dashboards in no time.

Data Visualization: What It Is and Why It Matters

What is data visualisation?

Data visualization translates complex data into intuitive visuals such as graphs, charts, infographics, dashboards or even animation. It’s not about making data just “pretty”. It’s about creating a visual shortcut from raw numbers to actionable understanding.

To clarify: you have a data table in front of you, with a bar chart beside it displaying the same information.

I bet it’ll take you far less time to grasp the chart than to make sense of the table, even though there is not much data here. Data visualization is not just about charts — it’s about clarity.

Why is data visualisation important?

Back in 2014 a team of neuroscientists from MIT found that the human brain can process an image in just 13 milliseconds, which is about six times faster than reading and understanding a medium-length sentence.

Best Data Visualization Tools by Webix

Before we jump into the list, let’s quickly outline the key criteria we, as developers, use to evaluate data visualization tools:

• Performance — handles large datasets without lag.
• Ease of Configuration — quick setup with progressive complexity.
• Customization — adapts visuals to branding and UX needs.
• Lightweight — doesn’t bloat the app or slow down load times.
• Integration — works smoothly with modern frameworks and existing codebases.

In Webix we design data visualisation tools that just work. No sacrificing performance, customization, or developer experience. Here are Webix’s best components for data visualization that does not require third-party bloat.

1. Webix Charts – Best Free JS Charting Library for Dashboards

If you are interested in the best free data visualisation tools you found the right article. I’ll start this list with Webix charts, most of them are available in the GPL version that is free. These are the core visualization components offering over a dozen chart types, including bar, line, area, pie, donut, radar, and scatter plots. Webix also allows you to show several charts in one and hide them by clicking on the legend.

Best for: Real-time dashboards, analytics, and reports

Why it’s great:

• 10+ chart types (bar, line, 2D and 3D pie, scatter, radar) with smooth animations.
• Sorting and filtering by using the corresponding Chart API
• Selecting data ranges with the help of a Rangeсhart
• Drawing by coordinates can be optionally connected into a line or a shape.

Pro tip: If you need super complex visualizations (like force-directed graphs), you might still need integration with charts like D3.js or Highcharts. But trust our web development experience, for 90% of dashboard needs, Webix does the job.

2. Webix DataTable with JS Sparklines – Visualize Data Inside Tables

In cases where separate charts aren’t required but a visual overview is still helpful, data tables with integrated elements become a smart solution. Here is when Webix shines, our JS DataTable can be equipped with sparklines, bar charts, or pie charts.
