One diagram, many pictures

Each shape can have its own image and label.

GO BEYOND BASIC BOXES

Why just describe it when you can show it?

Ordinary diagrams use boxes and arrows. UtilityGlen lets you go further by adding a different picture to each diagram shape or milestone. Build visuals that combine labels, relationships and images in one place.

Upload images to individual shapes

Add PNG, JPEG or WebP pictures to diagram elements, with a 5 MB limit per upload.

Edit visually, not just through text

Select a shape, rename it, move it around the canvas or drop a picture directly onto it.

Keep your visuals together

Embedded pictures are included when saving editable project files and exporting diagrams.

Creative idea: Create a team chart with individual portraits, a product workflow with screenshots or a project timeline with milestone images.

Chart vs. Diagram: What's the Difference?

These two visual formats are related, but they answer different questions. Picking the right one can make your message much clearer.

Use a Chart When...

Your main goal is to display numerical information and help someone understand quantities, patterns or comparisons.

You need to compare categories.

You want to show growth or decline.

You need to explain percentages.

You are exploring numeric relationships.

Example: Compare monthly revenue using a bar chart.

Use a Diagram When...

Your main goal is to explain connections, structures, sequences or the relationship between different ideas.

You are explaining a workflow.

You want to organize ideas.

You need to show a hierarchy.

You are mapping project milestones.

Example: Explain an approval process using a flowchart.

Easy rule: If the question is "How much?", "How many?" or "How has it changed?", try a chart. If the question is "How does it work?", "What connects?" or "What happens next?", try a diagram.

BUILT FOR DIFFERENT IDEAS

From classrooms to marketing plans, discover practical ways to use charts and diagrams every day.

Students & Teachers

Make study mind maps, science graphs, classroom charts, historical timelines and educational diagrams.

Business Teams

Visualize sales metrics, company structures, project workflows, department responsibilities and performance.

Marketing & Content

Illustrate campaign stages, website traffic, customer journeys, content plans and marketing results.

Product & Development

Plan release timelines, describe processes, map features, explain product structures and document team workflows.

SMALL CHANGES, BIG IMPACT

Design Better Charts & Diagrams

You don't have to be a designer to communicate visually. A few thoughtful decisions can make a chart more readable and a diagram easier to follow.

The golden rule

A useful visual should answer a question, not create more questions. Prioritize clarity before decoration.

01

Use a meaningful title

"Monthly Website Visitors" tells readers more than "Chart 1." Describe what the visual actually communicates.

02

Choose colors with purpose

Use distinguishable colors consistently. Pair colors with labels so important information isn't communicated through color alone.

03

Avoid unnecessary clutter

Too many labels, connections or categories can make a visual harder to understand. Keep only what supports your message.

04

Make your data honest

Verify values, avoid misleading comparisons and use consistent units. For bar charts, a zero baseline is generally important for fair comparisons.

05

Export for the destination

Choose SVG when you need artwork that scales cleanly. Choose PNG for convenient image sharing and placement in everyday documents.

THE FINISHING TOUCH

Download the Format That Fits

Finished visuals are useful in different ways. Here's how to pick the right export format for your next project.

PNG

Ready-to-Use Images

A widely supported image format suited to documents, slides and straightforward sharing.

Best for: presentations and everyday graphics.

SVG

Scalable Vector Graphics

A vector-based format that maintains sharpness when resized. Useful for web graphics and scalable illustrations.

YOUR WORK, YOUR BROWSER

Create Locally. Stay in Control.

The Chart & Diagram Maker processes chart data, diagram editing and image resizing locally in your browser rather than requiring a project upload to a cloud rendering service. Local draft recovery is available where browser storage permits.

Like other websites, the page may load site resources and scripts separately. The editor's local processing does not replace your browser's normal privacy and security settings.

Chart & Diagram Maker FAQ

Everything you need to know about creating, editing, customizing, saving and exporting your visualizations.

What is the UtilityGlen Chart & Diagram Maker?
UtilityGlen Chart & Diagram Maker is a free online visual creation tool that helps you turn data and ideas into charts and diagrams. It supports six chart types and four diagram types, with editing, styling and export options directly in your browser.
Is the Chart & Diagram Maker free to use?
Yes. You can create charts and diagrams using the browser-based editor without paying for a subscription or registering for an account to use the tool.
What types of charts can I create?
You can create bar charts, line charts, area charts, pie charts, doughnut charts and scatter plots. These options cover common uses such as comparisons, trends, category proportions and numerical relationships.
What types of diagrams can I make?
The editor supports flowcharts, mind maps, organizational charts and timelines. Use them to explain processes, brainstorm ideas, represent team structures and plan milestones.
Can I edit a chart directly in the preview?
Yes. Click supported chart elements such as bars, points, labels and pie slices to edit the associated values or text. You can also update the underlying chart data in the editor.
Can I move, rename and connect diagram shapes?
Yes. You can select and reposition diagram shapes, rename them, add new shapes, remove existing shapes and create connections through the diagram controls. Double-clicking a shape also provides a direct text-editing workflow.
Can I upload a different image for each diagram shape?
Yes. Select an individual shape or supported timeline milestone and upload an image for it. The editor accepts PNG, JPEG and WebP images up to 5 MB per upload. Images are processed locally and can also be dropped onto supported shapes.
How do I create a flowchart online?
Select Diagram mode and choose Flowchart. Start with an example or enter connections such as "Start -> Review" and "Review -> Finish". Then adjust the diagram, add shapes or pictures if needed, and export the result.
How do I make a pie chart from my data?
Select Chart mode and choose Pie Chart. Enter a column of category labels and a column of numerical values using comma-separated data. The editor generates the pie chart preview, which you can then customize and export.
Can I paste data from a spreadsheet?
Yes. The chart editor supports comma-separated and tab-separated data. You can copy an appropriate table from a spreadsheet and paste it into the data field. Make sure the headings, labels and numerical values are arranged correctly.
Can I change chart colors and backgrounds?
Yes. The editor includes Ocean, Vibrant, Forest, Sunset and Slate color palettes, along with white, transparent and soft-gray background choices. You can also control supported chart display settings such as labels, grids and legends.
Can I download charts and diagrams as PNG or SVG?
Yes. The editor provides PNG and SVG exports. PNG is a useful choice for general image sharing, while SVG is useful when you need a scalable graphic.
Can I save my work and edit it later?
Yes. You can save an editable JSON project file and reopen it in the tool later. The editor also supports local draft recovery where browser storage is available. Downloading a project file is recommended when you want a separate backup.
Does the tool work on mobile phones and tablets?
The interface is designed to adapt to mobile, tablet and desktop screens. The experience may vary depending on your browser, device performance and the complexity of the chart or diagram.
Does UtilityGlen upload my chart data or pictures?
The Chart & Diagram Maker performs its editor processing locally in your browser. Uploaded diagram pictures are processed there rather than being sent to a dedicated image-processing backend by the editor. Normal website resource and script requests remain separate from that local processing.
What is the best chart for comparing values?
A bar chart is usually a strong starting point for comparing values across categories. For changes over time, consider a line chart. For a small number of categories that together represent a whole, a pie or doughnut chart may be appropriate.
What is the difference between a mind map and a flowchart?
A mind map organizes related ideas around a central concept, making it useful for brainstorming and learning. A flowchart shows steps and connections in a process, making it better suited to workflows, procedures and decision paths.
Do I need any design or programming experience?
No. You can begin with built-in examples and edit the results through the interface. Basic familiarity with rows, columns and labels can help when creating charts from your own data.
