A chart builder is a visual tool that turns raw data from databases, spreadsheets, and PDFs into interactive charts and graphs. With Chart Builder, you can create colorful, interactive charts using a drag-and-drop interface and auto-generated PHP and HTML5 code—no coding or BI software required.

What is a Chart Builder?

A chart builder is a front-end, browser-based tool that connects to your data—MySQL, PostgreSQL, Oracle, Excel, CSV, or PDF—and turns it into stunning, interactive charts. Chart Builder pairs a drag-and-drop interface with a built-in SQL query generator, so you can retrieve complex data and visualize it in minutes, without writing code or hiring technical help.


Why Visualize Your Data

Instead of scanning rows in a spreadsheet or scrolling through a database table, a well-built chart shows you the trend, the outlier, and the pattern at a glance. Chart Builder lets you pull data straight from your database or file, plot it on any of 40+ Interactive Chart types, and share the result as a link, an image, or embeddable code—so the same chart that helps you spot a problem can just as easily go in a report or on a dashboard.

Chart Builder Requirements

Chart Builder is a lightweight utility built in a simple, prescriptive way, so it doesn't need lavish server requirements to run.

Server Requirements

  • PHP Version 7.2 or later
  • Apache or Nginx
  • Windows, Linux, or Ubuntu

Supported Browsers

  • Firefox 52 or higher
  • Chrome 57 or higher
  • IE 8 or higher

To connect to your database and retrieve chart data, make sure your web server is configured to serve the folder containing Chart Builder, with read-write permission granted (chmod -R 777) to the Chart Builder folder and sub-folders. Check your browser console to confirm all Chart Builder files load without errors.

11 Popular Chart Types Supported

Chart Builder brings all the most widely used chart types together in one place, so you can trace and measure your data from every angle. Select any of the following from the chart type drop-down:

11 Chart Types Supported in Chart Builder

Line & Bar Charts

A line chart connects data points to show trends over time—the most common and widely used chart type. A bar chart compares categories using rectangular bars, plotted vertically or horizontally.

Stacked Bar & Scatter Charts

Stacked bar charts compare categories while breaking each one down into parts of a whole. Scatter charts plot two variables against each other using Cartesian coordinates to reveal correlation.

Area & Donut Charts

An area chart is a line chart with the space beneath it filled in color to emphasize volume. A donut chart is a pie chart variation with a hollow center, useful for showing an additional metric.

Bubble & Gauge Charts

A bubble chart is a scatter chart where bubble size represents a third data dimension. A gauge chart uses a needle on a dial—perfect for a speedometer-style KPI on a dashboard.

Heatmap & Choropleth Map

A heatmap visualizes a data matrix using color intensity. A choropleth map shades geographic regions according to a data variable—ideal for regional sales or performance comparisons.

Sunburst Chart

A sunburst chart displays hierarchical data as a series of nested rings, showing how each outer ring (child) relates back to the inner rings (parent categories).

Chart Builder Best Practices

1. Match the Chart to the Data

Use line charts for trends, bar charts for comparisons, and gauge charts for single KPIs—don't force one chart type to do every job.

2. Keep Queries Focused

Use the SQL generator to pull only the columns you need for the X and Y axis, keeping charts fast and easy to read.

3. Test Before You Publish

Check your browser console for errors and confirm chart data loads correctly before sharing the link or embedding the code.

Publish and Share Your Charts

Publish and share your charts with a single click. Chart Builder generates a shareable URL for any chart you create, so your colleagues can view it instantly—no export or file transfer needed.

Chart Builder also generates ready-to-use PHP source code for every chart in one click. This auto-generated code is published under the MIT license, so you're free to customize it and embed it directly into your own PHP, WordPress, Joomla, or Laravel application.

Frequently Asked Questions

With Chart Builder, you build a chart in three steps: connect your data source (MySQL, PostgreSQL, Oracle, Excel, CSV, or PDF), retrieve your data using the built-in SQL generator, then drag and drop your columns onto the X and Y axis. No coding is required, and you can publish the finished chart as a shareable link or export ready-to-use PHP/HTML5 code.
Chart Builder includes a free, browser-based column (bar) chart tool that plots your data vertically or horizontally. Connect a database or spreadsheet, drag your fields onto the axis, and Chart Builder generates a fully responsive column chart you can download and self-host at no cost.
Chart Builder includes a free Pie chart maker, along with a Donut chart—a pie chart variation with a hollow center for showing an extra metric. Both are part of Chart Builder's full library of 20+ chart types. Connect your data source and drag your columns onto the chart to generate an interactive pie or donut visualization in minutes, no coding required.
Match the chart to the question you're answering: use a line chart for trends over time, a bar or column chart for comparisons between categories, a scatter or bubble chart for relationships between variables, a donut chart for proportions, a gauge chart for a single KPI, a heatmap for a data matrix, a choropleth map for geographic comparisons, or a sunburst chart for hierarchical data. Chart Builder supports all of these, so you can switch chart types from the same connected data without rebuilding your query.
You don't need to type a chart description at all. With Chart Builder's AI Dashboard Generator, you simply upload a PDF, Excel, or CSV file, and the built-in AI reads your data, selects the right chart types—including pie, bar, line, and donut—and builds a complete interactive dashboard automatically, with no SQL, drag-and-drop, or manual configuration required.
The best free chart creators let you connect directly to your data, offer more than one or two chart types, and don't force you into proprietary lock-in. Chart Builder connects to MySQL, PostgreSQL, Oracle, Excel, CSV, and PDF sources, supports 11 chart types, is free and open-source with the full code on GitHub, and exports PHP/HTML5 you can embed in WordPress, Joomla, Laravel, or your own PHP app.
