Five practical steps. No complicated setup or professional design training required.
Choose a chart for numerical data or a diagram for processes and ideas.
Enter chart data, start with example values or build a diagram using shapes.
Change labels, adjust values and customize diagram elements directly.
Choose a palette, set a custom title color and customize the background.
Download PNG or SVG, or save an editable project for future updates.
A polished chart is more than correct numbers. Its colors and typography help people understand what's important. Explore preset palettes, change individual data-series colors and choose a background that suits your report, website or presentation.
Choose from Ocean, Vibrant, Forest, Sunset, Slate, Pastel, Neon, Earth Tones, Candy, Royal and other available preset styling.
Choose your own series colors and use the title color picker to make headings match your brand or theme.
Switch between preset canvas backgrounds or choose a custom color for a more personalized result.
Sample title color
Make data look amazing.
Decorative color samples. Use the color controls in the live studio to customize your visualization.
Start with a small table of labels and values. A bar chart can compare months, while a line chart can show change over time. Chart data can be entered as comma-separated or tab-separated values.
Try a sample dataset, choose a chart type and edit values until the visualization reflects your real information.
Scatter plots use numeric X and Y values. Enter numbers in the first column when you want precise horizontal positions. If you switch from a categorical chart, the studio can map text categories to sequential numeric positions.

Edit supported chart labels and values in the preview. Select diagram shapes, rename them and arrange your design visually.
Add a different PNG, JPEG or WebP image to diagram elements. Bring team charts, project plans and workflows to life.
See changes as you edit. Explore layouts, compare chart types and fine-tune the look before downloading.
Experiment more confidently with editing history that lets you reverse and restore recent changes.
Download an editable JSON project and reopen it when it's time to make revisions. Local draft recovery also helps preserve work where supported.
Want a fresh start? The reset option clears this tool's saved browser draft and restores its default settings after confirmation.
Create graphics that help people learn, plan, communicate, explain and make decisions.
Study mind maps, research charts, scientific graphs and historical timelines.
Sales comparisons, organizational structures, dashboards and quarterly reports.
Campaign performance, audience insights, customer journeys and content plans.
Project milestones, decision flows, process documentation and improvement cycles.
Choose the format based on what you want your audience to understand.
Charts help answer questions about quantities, changes, rankings and numerical relationships.
Example: Compare monthly sales with a bar chart.
Diagrams help explain connections, sequences, workflows and the organization of ideas.
Example: Illustrate an approval process with a flowchart.
"Website Visitors by Month" is more informative than "Chart 1."
Keep the palette consistent and never rely on color alone to communicate categories.
Remove unnecessary labels, decorative shapes and excess connections.
Verify sources, units and scales. Use a zero baseline for standard bar-chart comparisons.
A chart that looks good on a large monitor may need simpler labels on a phone screen.
A widely supported raster image format, ideal for documents, presentations and ordinary image sharing.
A scalable vector format useful for websites and artwork that needs resizing without losing vector sharpness.
An editable project format. Save a copy and reopen it in the studio when you want to continue working.
Helpful tip: Keep the JSON project when you expect revisions, then export PNG or SVG for your final audience.
Chart generation, diagram editing and image processing take place in the browser. Local draft recovery can help restore recent work where browser storage allows. Save an editable project file when you want a separate backup. The Reset Studio control clears this tool's saved draft after confirmation, rather than deleting unrelated UtilityGlen storage.
Standard website resource requests and your browser's own privacy settings are separate from the editor's local processing.
EVERY QUESTION DESERVES A CLEAR ANSWER
Answers about charts, diagrams, custom colors, images, editing, export files and the online studio.
It's a free online visual editor for creating charts, graphs and diagrams. You can enter data, build flowcharts and mind maps, customize colors, edit visual elements and export your results.
Yes. The browser-based editor is available without a paid subscription or a mandatory account registration.
The studio supports vertical bar charts, horizontal bar charts, line charts, area charts, pie charts, doughnut charts, stacked bar charts and scatter plots.
You can create flowcharts, mind maps, organizational charts, timelines and cycle diagrams. These cover common needs such as explaining processes, organizing ideas, representing team structures and illustrating recurring workflows.
Yes. Supported chart elements can be selected for editing, including values and labels. You can also edit the underlying data to update the chart preview.
Yes. Select an individual diagram shape or supported milestone and add its own PNG, JPEG or WebP image. The tool processes uploaded pictures locally and includes the images in supported exports and saved projects.
Yes. In addition to the preset palettes, the studio offers custom series colors, a title color picker and a custom background color option. These settings let you tailor visuals for different documents, brands and presentations.
Select diagram mode and choose Flowchart. Add your steps, connect the relevant shapes, adjust labels and arrange the layout. You can personalize diagram nodes with pictures, then download the result as PNG or SVG.
Select chart mode, choose Pie Chart and enter category labels with their numeric values. Review the preview, customize its appearance and export your chart once the proportions are correct.
A scatter plot places points on numerical X and Y axes. Enter numeric values in the first column for precise X positions and the corresponding Y values in the next column. When switching from category-based charts, the studio can represent text labels as numbered positions.
Horizontal bar charts are especially useful for rankings and comparisons with longer category labels, such as product names, survey answers or department names.
Stacked bars show both a category's total and how multiple series contribute to that total. They work well for sales by region, spending by department and other breakdowns across categories.
A flowchart presents a process, usually with connected steps and decision paths. A mind map organizes ideas around a central topic, making it useful for brainstorming, learning and creative planning.
Yes. Use the title color picker to choose a custom heading color. The selected color is reflected in the preview and supported exports, and it can be retained in saved project files.
Yes. Save an editable JSON project, then use Open Project to reload it in the studio. Local draft recovery is also available when browser storage permits.
Choose Reset Studio and confirm the reset. The editor clears its own saved browser draft and restores default settings. It does not delete unrelated UtilityGlen tool data or previously downloaded project files.
Yes. PNG is convenient for sharing and embedding in everyday documents, while SVG is a scalable format often preferred for web graphics and vector-based artwork.
The layout is designed to adapt to phones, tablets and desktop browsers. The editing experience and performance may vary depending on your screen size, browser and the complexity of the project.
No. You can begin with built-in examples, edit values and use the studio's visual controls. Basic familiarity with your data and the type of information you want to communicate is enough to get started.
Transform raw numbers into meaningful graphs. Turn complex workflows into understandable diagrams. Make every visual feel like yours, then share the finished result with confidence.
