Mockup Studio: design charts without a file

Design instead of upload

No file required: enter values, pick a style and colours, done. Several styles (rounded, flat, gradient, minimal, outline), colour schemes and an optional render animation make every chart presentation-ready.

• Seven chart types including Sankey diagrams and a highlighted pie segment.
• Export as a single SVG or HTML file, as embed code, or as a complete offline dashboard.
• Every export is self-contained – no external fonts, no external scripts, privacy-friendly.

Ideal for presentations

Drop the export straight into PowerPoint, Keynote or your slides. Create clear charts for talks, essays and reports in seconds – with no file upload.

Full control over every detail

Unlike auto-generated charts, the Mockup Studio lets you set every value, label and colour yourself. Highlight individual segments, name series and categories freely, and switch between several styles until the graphic matches your slides exactly. Ideal when you want to show sample or estimated figures without building a real table first.
