Fork of Cars Scatter Plot

This scatter plot visualizes the relationship between a country's happiness Score and its perceived corruption level, using data from the World Happiness Report. Each red circle represents a country, positioned by its Score on the x-axis and corruption value on the y-axis. The code uses D3 v5’s `scaleLinear`, `axisLeft`, and `axisBottom` to construct the chart, with SVG rendering. It loads the `happiness.csv` file via `csv`, maps numeric fields, and applies margins, axis labels, and a title within the SVG canvas.

Project Increment 1

This radar chart compares the six happiness factors from the 2022 World Happiness Report across four rank groups of countries. The visualization shows averaged scores for GDP per capita, social support, healthy life expectancy, freedom, generosity, and perceptions of corruption, with distinct colored polygons representing top, mid-high, mid-range, and low-ranked nations. Built with D3 v7, the chart uses `d3.csv` for data loading, `d3.scaleLinear` for radial scaling, and SVG paths with `d3.line` for polygon generation. The data file uses comma-separated values with European decimal notation.

1027Happiness Level Line Chart

This visualization displays self-reported life satisfaction across countries from 2004 to 2017, using a scatter plot where each circle represents a country-year observation. Users select a metric from a dropdown menu, and clicking a color legend entry highlights that country’s points while dimming others. The D3.js v5 code employs `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and transitions to animate marks, with `interpolateRdYlBu` for color encoding. Data originates from the World Happiness Report 2017, rendered as an SVG with interactive legend and dropdown functionality.

Fork of veda_piechart7

This example shows a pie chart of GDP per capita from the 2019 Happiness Report, with each slice labeled by country or region and accompanied by a colored legend. Built with D3.js v6 and React, the chart uses `d3.pie()` to compute arc segments and `d3.arc()` for path generation, assigning colors via `d3.scaleOrdinal` with the `schemeCategory10` palette. Country labels are placed using arc centroids, and the legend maps colors to country names, all rendered as SVG elements within a 960x500 canvas.

1027Happiness Level Line Chart

This chart visualizes life satisfaction across multiple countries from 2004 to 2017, using data from the World Happiness Report 2017. Each country is represented as a line, with a dropdown menu to switch between different well-being metrics. A color legend allows users to highlight specific countries by clicking. The visualization uses d3.line with curveBasis for smooth paths, d3.nest for grouping, and d3.axisLeft/axisBottom with gridlines, rendered as SVG with animated transitions.

Happiness Level Chart

This visualization presents self-reported life satisfaction across countries from 2004 to 2017, using data from the World Happiness Report 2017. It combines a scatter plot with year and satisfaction metrics, a multi-line chart tracking trends per country, and an animated cartoon face that shifts expressions. Users select different satisfaction indicators via a dropdown menu and filter countries by clicking the color legend. The D3 v5 code builds SVG elements, uses scales like `scaleTime` and `scaleLinear`, and applies transitions to update data points and the face animation.

Happiness Level Line Chart

This line chart displays life satisfaction trends across countries from 2004 to 2017, using data from the World Happiness Report. A dropdown menu lets viewers switch between variables like GDP per capita, social support, and freedom, with each country represented by a colored line via d3.nest and d3.scaleOrdinal. The visualization uses d3.line with curveBasis for smooth paths, d3.axisLeft and d3.axisBottom with tick marks, and an SVG color legend. It renders as SVG with d3.v5, updating the view dynamically through a custom lineChart function.

pie chart

This pie chart visualizes the happiness scores of countries in Western Europe from the 2019 World Happiness Report. The visualization uses D3.js version 5 with an SVG rendering approach, employing `d3.pie()` and `d3.arc()` to generate slices, `d3.scaleOrdinal` with `schemeCategory10` for colors, and `arc.centroid` for label placement. Each slice represents a country, with its size proportional to the reported happiness score, while a legend identifies the color coding. The data is loaded directly from a CSV file hosted on GitHub.
