Resources

Practical guides, templates and tools to help journalists, researchers and students produce reliable data stories.

Learning goal: By using these resources you will be able to plan, clean, visualise and publish a basic data-driven story — from dataset to finished narrative.

Use the quick-start checklist below if you are publishing for the first time. These resources are intentionally lightweight and suitable for journalists working with limited internet bandwidth.

Quick Start — Core Steps

  1. Define the question — what do you want to prove or explain? (1–2 sentences)
  2. Find data — look for official sources, CSVs, budgets, public records.
  3. Clean data — remove duplicates, standardise dates, check for missing values.
  4. Analyse — simple counts, trends, and comparisons.
  5. Visualise — use charts or maps that match your question.
  6. Tell the story — combine visuals with context, sources and methodology.

Estimated time for a short data story: 1–5 days depending on data availability.

Tutorials (Beginner → Intermediate)

  • Data Journalism 101 — planning, sourcing, and ethics.
  • Cleaning Data — using Google Sheets, Excel and OpenRefine for common tasks.
  • Visualisation Essentials — choosing between line, bar, pie, and map visualisations.
  • Mapping basics — how to make a simple choropleth using a GeoJSON file and Leaflet.
  • Intro to Python for reporters — reading CSVs and producing summary tables with pandas.

Each tutorial includes a step-by-step example and suggested tools to use offline or on low bandwidth.

Tools & Platforms

  • Google Sheets / Excel — quick cleaning and pivot tables.
  • OpenRefine — powerful for reconciling names and cleaning messy columns.
  • Datawrapper — fast, no-code charts and maps for publishing.
  • Leaflet + GeoJSON — lightweight mapping for the web.
  • QGIS — desktop GIS for advanced spatial analysis.
  • GitHub — share datasets and version control for reproducibility.

Where possible, prefer open-source tools to keep costs low.

Ethics & Sourcing

  • Always cite the original data source and provide a link or downloadable file when possible.
  • Assess the reliability of official statistics — cross-check with multiple sources.
  • Protect vulnerable individuals — anonymise personally identifiable information (PII).
  • Document your methodology so readers and editors can verify results.

When in doubt, consult with a data editor or legal advisor before publishing sensitive material.

Mini How‑To: Clean a date column in Google Sheets

  1. Open your CSV in Google Sheets.
  2. Select the column with dates, click Format → Number → Date.
  3. Use =DATEVALUE(A2) to convert text to a date serial if needed.
  4. Sort and visually inspect for outliers (e.g., year 1900 or future dates).
// Example: Convert a date text '12/31/2021' in A2 to ISO in B2
=TEXT(DATEVALUE(A2),"yyyy-mm-dd")

Mini How‑To: Simple chart with Chart.js

Paste this snippet into a page that loads Chart.js (CDN) to create a basic bar chart.

<canvas id="chart" width="400" height="200"></canvas>
<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
<script>
const ctx = document.getElementById('chart');
new Chart(ctx, {
  type: 'bar',
  data: {labels:['2020','2021'],datasets:[{label:'Value',data:[325000,410000]}]},
});
</script>

Suggested Readings & Courses

  • Books: “The Data Journalism Handbook” (practical overview)
  • Free courses: Introductory modules on data analysis (checked on major MOOC platforms)
  • Practice: Reproduce a chart from a public report — it is the best way to learn.

If you would like specific course names or book links, we can add a curated list tailored to West African data sources.
