This example displays multiple line charts on a single SVG canvas, tracking the average human wellness index for four countries (India, Sri Lanka, Vietnam, Cambodia) from 2010 to 2019. It first establishes linear scales for time and wellness values, then uses d3.line with path elements to draw each country’s trend, colored via an ordinal scale. The code employs d3.axisBottom and d3.axisLeft for axes, plus the d3-legend library’s legendColor for a horizontal ordinal legend. Data is loaded from a remote CSV using d3.csv, with parsing and flattening for the y-domain.

D3 - Multi-Line Chart

This multi-line chart displays carbon dioxide emissions per country from 1970 to 1979, using four distinct colored lines with circular data points. The visualization loads CSV data from a GitHub gist and renders an SVG with a light gray background panel, axis labels, and a title. It uses d3.csv for data loading, d3.line to construct the paths, and d3.axisBottom and d3.axisLeft for the axes. Interactive tooltips appear on mouseover, showing the emission value for the hovered point, with circles enlarging to indicate selection. The chart also incorporates colorbrewer colors and the d3-legend library.

D3 Example

A small multiples line chart shows population growth from 1950 to 2015 for China, India, and the U.S. It uses D3 v3 with SVG, `d3.svg.line`, `d3.time.scale`, and `d3.legend.color`, rendering colored strokes per country. The y-axis uses a custom SI format (B for billions), and data loads from a CSV via `d3.csv`.

D3 Chart

This example displays six D3.js charts—horizontal and vertical bar charts, a line chart, an area chart, a pie chart, and a donut chart—all rendered as SVG elements. Each visualization uses the d3.csv function to load population data by country from a local CSV file. The code applies d3.scaleLinear and d3.scaleBand for axes, d3.line and d3.area with curveBasis for path generation, and d3.scaleOrdinal with schemeSet2 for categorical colors, while d3.axisLeft and d3.axisBottom create the tick marks.

project

A multi-line chart compares actual versus expected population figures for India, the USA, and China from 2015 to 2030. The visualization uses D3 v6 with SVG rendering within a React framework, with each country's actual and projected data drawn as distinct colored lines using `d3.line` and `d3.scaleTime`/`d3.scaleLinear` for axes. The code includes a tooltip and styles lines with the `.line` class. Data comes from a static CSV file containing yearly population values.

Fork of D3.js Line Chart

This chart shows the trend of Happiness Scores for China, India, and Japan over five years, drawing on data from the World Happiness Report. A single line is rendered using an SVG path generated by the D3.js `d3.line` function. The x-axis uses an ordinal scale (`d3.scaleBand`), while the y-axis is a linear scale (`d3.scaleLinear`); both axes are created with `d3.axisBottom` and `d3.axisLeft`. The visualization aggregates the data to show the overall score trajectory, though it does not distinguish between the three countries in its line presentation.

multi line chart- d3

This multi-line chart visualizes changes in six continental populations—Africa, Asia, Europe, North America, Oceania, and South America—over time using data loaded from a remote CSV file via `d3.text`. The code renders six distinct colored lines using `d3.line` paths within an SVG, with each region assigned a unique stroke color. The chart uses `d3.scaleBand` for x-axis months and `d3.scaleLinear` for y-axis values, which is fixed between 1,000 and 3,600,000. Interactive circular markers, created with SVG `circle` elements, display tooltips on mouseover via `d3.select` and event listeners, showing the specific data values for each month. The visualization is built with React, utilizes D3.js version 7, and is rendered entirely as vector graphics.

D3 - Small Multiples Line Chart

This example shows a series of small multiples line charts, each depicting CO2 emissions over time for a specific country. The D3.js code (version 7) loads data from a CSV file and uses `d3.scaleLinear` for axes, `d3.line` for the line paths, and `d3.legendColor` for a legend. It renders as SVG, with interactive hover tooltips revealing emission values per year.

Line Chart with Multiple Lines

This example displays suicide numbers across countries over time, with each country’s yearly data shown as a separate colored line and a matching color legend on the right. Using d3.csv to load the dataset, d3.scaleTime and d3.scaleLinear map years and suicide counts, while d3.nest groups records by country and sorts them by the last value. The SVG rendering includes axes, gridlines, and a title, though the line paths are commented out, so only colored circles appear at data points.
