This example visualizes abortion rates for 15-17-year-olds across eight U.S. states from 1985 to 2017 as a multi-series line chart, with each state distinguished by a color-coded ordinal scale and a d3-legend. It renders using SVG with animated tooltips on circular data points that display the year, state, and rate on mouseover. The visualization is built with D3 v7, using d3.group for data nesting, d3.line for path generation, d3.scaleLinear for axes, and d3.axisBottom/Left for tick marks, drawing from CSV data loaded via d3.csv.

Line Chart with D3

Inspired by:

And by documentation:

Tooltip shifting: for unknown reason vizhub shows tooltip shifted to the left, but locally in Chrome and Safari browsers tooltips work fine, I suspect there may be a bug in vizhub. If there is a valid explanation, please share!

Bar Chart with a Sequential Color Scale with D3

This bar chart displays abortion rates for 15–17-year-olds across U.S. states in 2010, using a sequential color scale from light blue to dark blue to encode rate values. Each state’s bar is colored via `d3.scaleSequential` with `d3.extent` domain, and an interactive tooltip appears on mouseover. The visualization uses D3 v7 to render SVG elements, including axes via `d3.axisBottom` and `d3.axisLeft`, plus a color legend from the `d3-legend` library. Data is loaded from a CSV file using `d3.csv`.

Line Chart Using a Qualitative Color Scale with D3

This line chart tracks abortion rates over time across multiple U.S. states, with each state represented by a separate colored line using a qualitative Set1 color scale from ColorBrewer. A legend to the right identifies each state, and hovering over individual data points reveals an interactive tooltip with the year, state, and rate. The visualization is built with D3 v7, using `d3.scaleOrdinal` for color assignment, `d3.line` for path generation, and SVG rendering with animated tooltip transitions.

Heatmap with D3

This heatmap visualizes abortion rates per 1,000 women aged 15–17 across U.S. states over multiple years, using a linear color scale from light gray to red to indicate rate intensity. The D3 v7 code loads data from a CSV and renders an SVG with `d3.scaleBand` for the x- and y-axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.scaleLinear` for color encoding. It appends rectangles for each state-year pair, plus a legend and axis labels.

Line Chart with Multiple Lines

This line chart displays the count of a phenomenon across U.S. states, grouped by region (South, West, Midwest, Northeast) over five years (2011–2015), with each region represented by a distinct colored line. The visualization uses D3 v5’s `nest()` and `rollup()` to aggregate state-level data from a CSV file, then renders paths with `d3.line()`. It employs `scaleTime`, `scaleLinear`, and `scaleOrdinal` with `schemeCategory10` for axes and color encoding, plus a custom `colorLegend` component for region labels. SVG rendering includes axis labels and a title, with data sourced from the Data Canvas - Sense Your City project.

Fork of HTML Starter

This scatter plot visualizes birth rate trends for U.S. states, comparing 2017 values on the x-axis against 2018 values on the y-axis, with each state represented as a green dot. The visualization uses D3.js v6 to load CSV data from a GitHub gist, parse it, and render an SVG chart with labeled axes. The code implements linear scales with `d3.scaleLinear`, draws axes via `d3.axisBottom` and `d3.axisLeft`, and creates circles with `append('circle')`. Interactive mouseover events log state-specific data to the console.

A7 Small Multiples Line Chart

This small-multiple line chart displays marijuana usage rates per 1000 people for ages 18–25 across US states, using data from the CORGIS dataset. Each state’s trend line is rendered in its own SVG cell, colored via a d3.scaleOrdinal palette, with a d3-legend color threshold legend. The visualization uses d3.group to separate data by state, d3.line to create paths, and d3.axisBottom and d3.axisLeft for axes, with a title overlaid in HTML.

A7 Multi-Line Chart

This chart visualizes violent crime rates per 100,000 people across U.S. states from 2000 to 2019, using data from the CORGIS dataset. Each state is shown as a multi-line path with colored dots for individual data points, and hovering reveals exact values. The visualization is built with D3 v7, using `d3.csv` for data loading, `d3.line` for path generation, and `d3.legendColor` from the d3-legend library for the color legend. Axes are rendered via `d3.axisBottom` and `d3.axisLeft`, with an ordinal color scale distinguishing states.

Visualization 2 (Multiline graph)

This chart displays population distributions for six U.S. states, broken down into seven age groups. A grouped bar chart, it uses horizontal positioning for states and color-coded bars for each age bracket, with a legend on the right. The visualization loads CSV data via `d3.csvParse` and renders SVG elements using D3 v5, employing `d3.scaleBand` for the x and subgroup positions, `d3.scaleLinear` for the y-axis, and `d3.axisBottom` and `d3.axisLeft` for the axes.
