storytelling-with-data_skill

Overview

This skill applies the Storytelling with Data (SWD) six-lesson framework to create, review, and improve data visualisations and data-driven communications. It focuses on clarifying the single takeaway, choosing the right visual, decluttering, guiding attention, applying good design, and structuring a narrative arc. Use it for charts, dashboards, infographics, slide decks, reports, or data-driven web pages. The guidance is format-agnostic and pairs with format-specific tools for implementation.

How this skill works

I start by clarifying context: audience, the one action or takeaway, and the delivery medium. Then I pick the simplest effective visual for each message, remove unnecessary elements, and apply a grey-plus-one-accent colour strategy to direct attention. I ensure each panel or slide has a declarative title, readable annotations, and a clear narrative flow (setup, tension, resolution). For reviews or makeovers I provide concrete before/after recommendations and a short checklist of fixes.

When to use it

• Creating new charts, dashboards, infographics, slide decks, or data-driven pages.
• Reviewing existing visuals to improve clarity, impact, or accessibility.
• Performing chart makeovers to simplify, declutter, and highlight the key message.
• Choosing the right chart type and visual strategy for a specific audience and goal.
• Advising how to structure a narrative or sequence of panels/slides for persuasion.

Best practices

• Start with audience + one-sentence "big idea" before touching a tool; storyboard first.
• Match visual type to message (bars for comparison, lines for trends, text for single KPIs).
• Eliminate clutter: remove unnecessary borders, gridlines, markers, and redundant labels.
• Use grey for defaults and one accent colour to highlight what matters; label directly where possible.
• Give every chart a declarative action title and add concise annotations to explain the "so what".
• Design for accessibility and progressive disclosure based on whether a presenter will narrate the visuals.

Example use cases

• Turn a dense monthly sales dashboard into an executive-ready overview with drill-down panels.
• Make over a multi-line 'spaghetti' chart into small multiples or focused comparisons.
• Convert exploratory analysis into an explanatory slide deck with a clear beginning–middle–end narrative.
• Design an infographic that reads top-to-bottom with clear section headers and a single accent colour.
• Review an emailed report and add annotations and declarative titles so it stands alone without a presenter.
