Tableau Projects - Data Technician Bootcamp

Welcome to my Tableau projects page.

Overview

Tableau is a powerful data visualisation tool I use to transform datasets into interactive dashboards and clear, meaningful insights. I work across the full workflow: connecting to data sources, cleaning data, building calculated fields, designing visuals, and publishing dashboards that support decision‑making.

Core Skills

Interactive Dashboards — filters, slicers, parameters, actions
Calculated Fields — logic functions, aggregations, table calculations
Data Preparation — joins, blends, unions, data cleaning
Visualisation Design — bar charts, line charts, maps, scatter plots, KPIs
Storytelling — building multi‑page stories and insight‑driven layouts
Performance — optimising extracts, reducing load time
Publishing — Tableau Public dashboards, sharing, embedding

UK Employment Dashboard

This dashboard analyses employment trends across the United Kingdom from 2011 to 2014. It highlights regional changes using an interactive UK map, bubble charts, and industry‑level breakdowns. Users can explore average percentage changes across sectors, identify the top industries with rising employment, and compare the fastest‑growing cities. The dashboard provides a clear, data‑driven view of how employment shifted across the UK over time.

Global Health Insights Dashboard

This dashboard visualises global health indicators to reveal patterns in life expectancy, population distribution, and health outcomes across regions. It combines bar charts, scatter plots, and geographic maps to show relationships between variables such as BMI, cholesterol, and life expectancy. The dashboard helps users compare countries, identify disparities, and understand how health metrics vary across continents.

Spotify Insights

This dashboard explores music streaming trends using Spotify audio feature data. It highlights genre popularity, track characteristics, and user listening behaviour through line charts, bar charts, and treemaps. Users can analyse patterns in danceability, tempo, energy, and popularity across genres and artists. The dashboard provides a clear overview of how musical features influence listening trends and playlist performance.
