Data Visualisation in Swansea
Charts and visual reporting that make a point for Swansea organisations. Most business charts fail not because they are ugly but because the chart type fights the question — a pie chart comparing eleven categories, or a dual axis chosen to make two unrelated series appear to move together.
Why this comes up
The problem
The analysis is sound and the charts do not land. Meetings spend their time interpreting the graph rather than discussing what it shows.
What you get
What we deliver
- Chart types chosen for the comparison being made, not for variety
- Axes and scales that represent the data honestly
- Colour used to carry meaning, and checked for colour-vision deficiency
- Annotation, so the point is stated rather than left to be inferred
- Accessible output, including for readers using assistive technology
- Reusable templates, so future charts follow the same conventions

Data Visualisation in Swansea — common questions
- What is the most common charting mistake?
- Using a chart type that does not match the comparison — pies for many categories, dual axes implying a relationship that does not exist, or truncated axes exaggerating a difference. Most of these are habits rather than decisions.
- Should a bar chart always start at zero?
- For bars, yes — their length is the comparison, so a truncated axis misrepresents it. Line charts showing change over time are different, where a zero baseline can flatten the pattern you need to see. The rule is about what the reader is comparing.
- How should we use colour?
- Sparingly and meaningfully — to distinguish categories or highlight one series, not to decorate. Check contrast and colour-vision deficiency, since red-green combinations are unreadable for a meaningful share of any audience.
- Do charts need to be accessible?
- Yes, and in the public sector it is a legal requirement. That means sufficient contrast, meaning not carried by colour alone, and text alternatives conveying the finding rather than describing the picture.
- Do you work with businesses across Swansea?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Swansea and the surrounding Swansea area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Swansea businesses do you usually work with?
- Bilingual public-facing systems for institutional clients, and seasonal booking for the Gower tourism trade. Beyond that we work across Higher Education, Healthcare, Manufacturing, Tourism and Public Sector.
- Do you cover the areas around Swansea?
- Yes — we work throughout Wales, including Cardiff, Newport. Swansea is an urban area of roughly 240,000+, and we take on work across the wider Swansea region rather than the city boundary alone.
