A line chart displays happiness levels (life ladder scores) over time for many countries, with each country as a colored line and a color legend. The chart uses d3.line with curveBasis for smooth paths, d3.scaleTime and d3.scaleLinear for axes, and d3.nest to group data by country. Data comes from the World Happiness Report 2018 CSV, rendered as SVG with axes and gridlines.

Happiness Level Line Chart - Test

This visualization displays the happiness levels of 163 countries over time, using a line chart where each line represents a country's trajectory. Users can interact with a dropdown menu to select a specific country, and the color legend allows filtering by country. The chart updates dynamically with transitions. The code uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `scaleOrdinal`, `nest`, `line` with `curveBasis`, and `axisLeft`/`axisBottom`. The data comes from a CSV file, and the rendering uses SVG with animation.

Happiness Level Line Chart

This interactive line chart visualizes self-reported life satisfaction across the world from 2004 to 2017, using data from the World Happiness Report 2017. A dropdown menu lets viewers switch between different happiness-related metrics, such as GDP per capita, social support, and freedom, with each selection redrawing the SVG line chart. Built with D3.js v5, it uses `scaleTime`, `scaleLinear`, axes, and a `line` generator with `curveBasis` to render smoothed paths. The visualization encodes the selected metric over time, revealing trends and patterns in global well-being.
