Tableau — interactive dashboards
Tableau — interactive dashboards
Two published dashboards, built so the visuals read in sequence rather than being browsed at random.
Global Health Insights
Global Health Insights
Acting as an analyst for a global health organisation needing to understand health trends and disparities across countries and continents. Five worksheets were combined into one dashboard, with a Country filter and Continent and Gender colour legends exposed as dashboard controls, plus a phone layout alongside the desktop one.
Life Expectancy by Continent as a sorted horizontal bar for the latest year. Life Expectancy Trend as a line chart limited to the Top 5 countries with country on colour. Population by Gender as a pie chart labelled as percentage of total. Life Expectancy vs BMI as a scatter with country on detail and continent on colour. Blood Pressure by Continent as a self-directed extension visual.
Findings
Findings
Life expectancy varies markedly between continents and improves over time in the highest performers.
Population splits close to evenly by gender — approximately 50.6% against 49.4%.
Europe records the highest average blood pressure among the continents charted.
The scatter plot shows a relationship between BMI and life expectancy — an association only, not evidence of causation.
A health service such as the NHS could use a dashboard of this shape to identify health inequalities, compare population groups, target prevention programmes and monitor change over time.
Spotify Audio Features
Spotify Audio Features
Open exploration of Spotify track features with no fixed brief — average popularity by genre as a sorted bar across 26 genres, danceability against popularity as a scatter with genre on colour, and energy against valence as a bubble scatter with popularity on size.
Pop, Rap and Rock record the highest average popularity. Danceability shows a slight positive relationship with popularity, but with enough exceptions that it does not predict success on its own. Most genres cluster around medium-to-high energy and moderate valence.
Techniques
Techniques
Top N filters, single-value dropdowns, dashboard-level filters applied across several worksheets, Quick Table Calculations converting a sum to Percentage of Total, and deliberate use of AVG over SUM so averages are not distorted by differing row counts per country and year.
