This visualization plots the correlation between a country's happiness score and its health expenditure per person, using a scatter plot of circles and an overlaid linear regression trendline. The data is loaded from a CSV file via `d3.csv` and rendered as SVG. The least-squares computation is performed manually in `index.js` to calculate slope, intercept, and r-squared, which are then used to draw the line via `d3.svg.line` and the `d3.scale.linear` axis scales.

Linear Regression Line with D3.js

This example shows the correlation between a country’s happiness score and its health expenditure per person using a scatter plot with a linear regression trendline. The visualization, built with D3.js v3 and SVG, plots each country as a green circle, with axes labeled in dollars and happiness scores, and overlays a blue best-fit line computed via a least-squares function that returns the slope, intercept, and R-squared value. Data is loaded from a CSV file hosted on GitHub, while the regression calculation uses native array methods like `map` and `reduce`.

World Happiness and Health Expenditures Correlation

This visualization uses a line mark to plot the correlation between a country’s happiness score and its health expenditure per person, with points aggregated by average and the y-axis not starting at zero. It loads CSV data via `d3.csv` from a GitHub gist, then renders the chart using Vega-Lite API functions like `vl.markLine` and `vl.encode`, with a custom config for font sizes and axis styling. The code also includes a commented-out least-squares regression layer and tooltip setup via vega-tooltip, though the active view only displays the basic trend line.

Fork of World Happiness and Health Expenditures Correlation

This visualization shows the correlation between national happiness scores and health expenditures per person, using a line chart to depict the trend across countries. It loads country-level data from a CSV file and renders it with Vega-Lite, using vega-lite-api and d3.csv for data fetching. The chart is customized with config.js for readability, and includes a layer for a least-squares regression line exported from lregression.js, which calculates the linear relationship fit to the data points.

Scatter plot with D3.js!

This scatter plot displays the happiness scores of ten countries, with each country positioned along the y-axis and its score plotted on the x-axis. The visualization is rendered as an SVG using D3.js v5, employing `scaleLinear` for the x-axis and `scalePoint` for the categorical y-axis. Data is loaded from a CSV file via `d3.csv`, and axes are generated with `axisBottom` and `axisLeft`. The chart includes labeled axes and a title, with gridlines created through tick sizes.

Untitled

This scatter plot displays the relationship between a country's Happiness Score and its rate of depressive disorders, with each point's size representing population and color encoding geographic region. The visualization uses d3.csv to load the data, d3.scaleLinear for both axes, and d3.scaleOrdinal for the categorical color mapping. SVG circles are positioned via the xScale and yScale functions, with axis labels and tick marks generated using d3.axisBottom and d3.axisLeft within a React-rendered SVG container.

Scatter plot with D3.js!

This scatter plot displays the happiness scores of ten countries, showing each nation’s score along the horizontal axis with country names on the vertical axis. The visualization uses D3.js v5 with an SVG rendering approach, loading data from a CSV file. The code employs `d3.csv`, `scaleLinear`, and `scalePoint` to map scores and countries, while `axisBottom` and `axisLeft` generate the axes with tick lines. Circles are appended for each data point, styled with steelblue fill and opacity.

Fork of regression

A scatter plot compares GDP to health expenditures across countries, with a regression line showing their correlation. A checkbox toggles a logarithmic scale for the x-axis, which compresses the skewed GDP distribution. Point radius encodes each country’s World Happiness Score. The chart uses D3 v3/v4 with `d3.svg.axis`, `d3.scale.linear`, and a custom least-squares function for the regression. Data comes from the World Happiness Report, loaded via `d3.csv`.

Small Multiple Plots with D3.js

This visualization displays small multiple scatter plots, each representing a country's happiness score against its economy, with points colored by region. The plots are generated from a CSV file using D3 version 6's `d3.csv` fetch method, with scales created via `d3.scaleLinear` and `d3.scaleOrdinal` using the `schemeCategory10` color palette. Each SVG is built with D3's selection API, and axes are drawn using `d3.axisBottom` and `d3.axisLeft`. The title for each plot combines the ageStandard and Allages fields.
