This visualization depicts the top 10 countries in the 2022 World Happiness Report, using a world map with each country filled according to its happiness score and a red circle sized proportionally to that score placed at the country’s centroid. The map uses an equirectangular projection with a graticule, and the data, from a Kaggle dataset, is loaded via `d3.json` and `d3.csv`. The code leverages D3’s `geoPath`, `geoEquirectangular`, and `geoGraticule` APIs, along with TopoJSON to convert the world-110m TopoJSON into GeoJSON for rendering as SVG paths.

World Happiness Report 2022

This interactive visualization of the World Happiness Report 2022 displays a rotating orthographic globe using `d3.geoOrthographic` and `d3.geoPath`, with country circles scaled and color-coded by happiness score. It includes side panels with donut charts for top and bottom-ranked countries, scatter plots analyzing factor correlations, and a legend that filters highlighted circles by score ranges via `updateFilteredCircles`. Data comes from the World Happiness Report 2022 dataset, with SVG rendering and animations for hover interactions.

Happiness Factors Viz

This visualization displays the World Happiness Report 2022, plotting happiness scores for countries on an orthographic globe projection using d3.geoOrthographic and d3.geoPath. Circles sized by happiness score and colored by range bands appear on the map, with interactive tooltips and a legend for filtering by score. The visualization also includes side panels highlighting the top and bottom five happiest countries with flag icons, and a button to explore additional happiness factors from the dataset.

World Happiness Scores by Population

This visualization maps world happiness scores by population, with each country represented by a circle whose area is proportional to its population and whose color encodes its happiness score. Hovering reveals the country name and score, while clicking and pan/zoom allows closer inspection. Built with D3 v5, it uses d3.geoNaturalEarth1 and d3.geoPath for map rendering, d3.scaleSqrt for circle sizing, d3.scaleSequential with interpolateInferno for color, and d3.zoom for interaction. Data comes from the World Happiness Report, processed from CSV and TopoJSON sources.

World Happiness Scores by Population

This visualization maps world happiness scores by population, with each country represented by a colored circle whose area reflects its population. Clicking a circle reveals the happiness score, while hovering displays additional details, and pan/zoom enables closer inspection. The D3.js implementation uses `geoPath` with `geoNaturalEarth1` projection, `scaleSqrt` for circle sizing, and `scaleSequential` with `interpolateInferno` for color encoding. Data comes from the World Happiness Report via a CSV file, rendered as SVG with TopoJSON country boundaries.

World Happiness Ranking

This example visualizes the World Happiness Report 2017, ranking 155 countries by happiness scores. Using D3 v4 with SVG rendering, the visualization likely presents a bar chart or similar ranking display where each country's happiness score determines its position. The data comes from Kaggle's World Happiness dataset, which is based on a survey ranking countries by happiness levels. The visualization was built from scratch by the author to learn D3, using the classic bar-chart idiom to encode the happiness score, with the ranking clearly conveyed through the vertical ordering of the bars. The code is structured as a reusable block, making it easy to adapt for other datasets or analysis purposes.

World Happiness Scores by Population

This visualization displays world happiness scores for 156 countries, with circle area encoding population size on a natural Earth projection using d3.geoNaturalEarth1 and d3.geoPath. Pan and zoom interactions are enabled via d3.zoom, while hovering reveals country names and happiness scores, and clicking provides additional detail. Circles are scaled with d3.scaleSqrt, and the size legend uses d3.format for population labels. Data comes from the World Happiness Report, joined to TopoJSON country geometries, with rendering in SVG.

World Happiness Scores by Population

A world map uses colored circles to display the happiness scores of countries, with the area of each circle encoding population size. Users can pan, zoom, and hover over circles to see additional details. The map is rendered using SVG with the D3.js library, including geospatial projections and interactive zoom. Data is sourced from the World Happiness Report, and colors are applied via a sequential color scale for the happiness score legend.

World Happiness Scores by Population

This visualization displays world happiness scores for 156 countries, with circle size representing population and hover tooltips revealing happiness scores. Users can pan and zoom using d3.zoom. The map uses d3.geoPath with a Natural Earth projection, while population circles are sized with d3.scaleSqrt. Country boundaries come from TopoJSON data, and happiness scores originate from CSV data in the World Happiness Report. A custom sizeLegend displays population values, and color-coded countries distinguish those with missing population data.
