Fork of D3.js Line Chart

Fork of Making A Bar Chart

This bar chart displays Happiness_Score values for countries from a CSV dataset, using horizontal bars with a linear x-scale and banded y-scale. It shows one bar per country, with the bar length encoding the happiness score. The visualization is rendered as SVG using D3 v7, employing `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the axes and rectangles. The code loads data via `d3.csv` and applies a margin-based layout within a fixed 960×500 viewport.

This visualization shows how a selected country’s happiness and its contributing factors (economy, family, health, freedom, trust, generosity) change from 2015 to 2023, either as raw scores or as differences from the global yearly average. The user can switch between these two modes via a flag. The chart renders multiple colored lines, one per feature, using d3.line and d3.scaleOrdinal with d3.schemeSet2, and includes axes from d3.axisBottom and d3.axisLeft. Data comes from the CSV file, which is loaded with d3.csv.

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 - Test

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.

D3 - Line chart (multiple)

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.

Fork of linechart

This line chart displays the population of five selected countries—India, the United States, China, Japan, and Germany—from 2011 to 2021. It loads comma-separated data via `d3.text`, parses it, and renders multiple lines using `d3.line` with `d3.curveLinear`. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, and a legend lists each country’s color from `d3.scaleOrdinal` with `d3.schemeCategory10`. The visualization uses an SVG rendering approach within a fixed-width container, labeling the y-axis in billions.

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.

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.
