This example shows annual changes in forest area for six South American countries from 1990 to 2015 as a multiline chart, with each country as a colored line. The chart uses a time-scaled x-axis and a linear y-axis, with a legend mapping country names to colors. The code loads data from a CSV file using `d3.csv`, then applies `d3.scaleTime`, `d3.scaleLinear`, and `d3.line` to build the paths. Country lines are grouped via `d3.nest` and have interactive tooltips that appear on hover, with transitions handled through `.transition().duration(500)`. The rendering is SVG, with a static title and varying legend spacing.

Multiline chart with interaction

This multiline chart displays annual changes in forest area for South American countries from 1990 to 2015, with each country represented by a colored line. The visualization uses d3.nest to group data by country and d3.scaleOrdinal with d3.schemeCategory10 for color assignment. Hovering over any line triggers a yellow tooltip via d3.event listeners, showing the entity name. The chart is rendered as SVG using d3.line, d3.scaleTime, and d3.scaleLinear, with data loaded from a CSV via d3.csv.

Multiline chart with interaction

This example shows how South American countries’ annual changes in forest area have evolved over time, with each country represented as a distinct colored line. The chart uses React with d3.v5, rendering an SVG multiline chart with a time-scaled x-axis and linear y-axis. The code uses d3.line and d3.nest to structure the CSV data by entity, d3.scaleOrdinal and d3.schemeCategory10 for colors, and adds reactive tooltips via mouseover, mousemove, and mouseleave events on each path. The visualization includes a legend and title, with data loaded from a GitHub gist.

Assignment 6 -- Multiline chart with a qualitative color scale

A multiline chart shows annual net forest conversion for South American countries from 1990 to 2015, with each country’s time series drawn as a separate line using a qualitative color scale via d3.scaleOrdinal and d3.schemeCategory10. The visualization uses d3.csv to load the data, d3.nest to group by entity, and d3.line with d3.scaleTime and d3.scaleLinear for axes. SVG paths render the lines, and hover interactions trigger a yellow tooltip displaying the country name. The chart includes a legend and title, with the y-axis domain set from the minimum value to zero.

Fork of Multiline chart

A multivariable line chart tracks annual net forest conversion for six South American countries from 1990 to 2015, with each country’s trend shown as a colored path against a time-scaled x-axis and a linear y-axis ranging from the minimum value to zero. The visualization uses d3.csv to load the data, d3.nest to group rows by entity, and d3.scaleOrdinal with d3.schemeCategory10 for color assignment. Hovering a line triggers a yellow tooltip displaying the entity name, implemented via mouseover, mousemove, and mouseleave events. The chart is rendered as SVG with static axes and a legend, from data sourced in linechart.csv.

line chart Saranya

This example shows how forest area in South American countries has changed annually from 1990 to 2015, with each country’s net forest conversion trend drawn as a separate blue line. The chart uses d3.csv to load the data, d3.timeParse and d3.scaleTime for the year axis, and d3.nest to group values by country. A d3.line generator creates the SVG paths, while d3.scaleOrdinal assigns distinct colors to each country. Interactive tooltips appear on hover, and the chart includes a title and legend built with SVG text elements.

line chart Saranya

A multi-line chart displays annual net forest conversion for Peru, Ecuador, and Colombia from 1990 to 2015, with each country shown as a colored line with a label legend. The visualization uses D3 v5 with d3.line, d3.scaleTime, and d3.scaleLinear to map years and forest values, while d3.nest groups the CSV data by country. SVG paths render the lines, and hover tooltips reveal the country name. The chart reads data from a local CSV file and uses d3.schemeCategory10 for color assignment.

Multiline chart

This multiline chart displays profit trends across regions over time, with each line representing a region and colored via a categorical scale. Built with D3 v5, the visualization uses `d3.nest` to group data by region, `d3.line` with `d3.curveBasis` for smooth paths, and custom axis and legend components. The data, sourced from Data Canvas - Sense Your City, is loaded from a CSV and rendered as SVG.

Multing Data for Multiple Lines

This chart displays population estimates and projections over time for various world regions. A legend uses color to distinguish the regional lines. The data is loaded from two CSV files and processed with the `melt` function. The visualization is rendered as an SVG using D3 v5, employing `scaleTime`, `scaleLinear`, and `axisBottom` for axes, and `line` with `curveBasis` for the curves. The lines are colored using `schemeCategory10` and the chart includes a custom color legend.
