This diverging bar chart visualizes changes in violent crime rates across U.S. states between 2000 and 2019, using a red-blue color scale to distinguish increases from decreases. The chart shows both positive and negative changes diverging from a central zero axis, with state labels positioned on the appropriate side of each bar. Built with D3 v7, it uses `d3.scaleDiverging` and `d3.scaleThreshold` for color mapping, while `d3.legendColor` renders the threshold legend. Data comes from the CORGIS dataset, and hovering reveals precise values. The visualization employs an SVG container with a centered y-axis and responsive sizing based on window dimensions.

AI-generated description

Visualization of crime rate differences by state from the CORGIS dataset made with D3. Color legend and threshold code from Susie Lu.

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.

Line Chart

This line chart displays violent crime rates per 100,000 people for each U.S. state from 2000 to 2019, using data from the CORGIS dataset. Each state is represented by a colored line, with a color legend on the right for identification. Built with D3.js (v7), the visualization uses `d3.scaleLinear` for axes and `d3.scaleOrdinal` for color assignment, rendering paths and hover-able circles in SVG. The `d3.legendColor` API adds the threshold legend, and tooltips reveal exact values on hover.

Diverging Bar chart in D3

This diverging bar chart visualizes population percent changes across U.S. states between April 2020 and July 2019, using horizontal bars that extend left or right from a central zero axis. The visualization first loads CSV data via `d3.csv`, then applies `d3.scaleLinear` for axes and bar lengths, `d3.scaleBand` for the categorical y-axis, and `d3.scaleSequential` with an `interpolateRdBu` color scheme. A color legend is generated using `d3.legendColor` from the d3-legend plugin, while bars are rendered as SVG `<rect>` elements. The chart includes axis labels, a title, and subtitle, all styled with D3 v7.

EDAV 2022 TTh Project Group 31

This interactive bar chart compares violent crime rates per 100,000 population across 15 U.S. states and the District of Columbia for 2002 and 2014. Clicking the gray year label toggles between the two datasets, animating bar heights and colors via D3 v7 transitions. The chart uses `d3.scaleBand` and `d3.scaleLinear` for axes, with SVG rectangles rendered through `d3.selectAll` and a custom `update` function. Axis labels and margins are configured manually; data appears hardcoded in arrays rather than loaded from an external file.

Diverging Bar chart in D3

A diverging bar chart displays the population percent change across U.S. states, using the State Demographic dataset from the U.S. Census Bureau. The chart shows each state’s population change from April 1, 2020 to July 1, 2019, with positive changes extending right and negative changes extending left from a central zero axis. D3 v7’s `scaleLinear`, `scaleBand`, and `scaleSequential` with an `interpolateRdBu` color scheme map values to positions and colors, while the `d3.legend` plugin adds a color legend. Data is loaded as CSV via `d3.csv` and rendered as SVG rectangles.

A6 - Diverging Bar Chart

This diverging bar chart visualizes the change in state population from 2020 to 2023, using a diverging color scale to distinguish growth (steelblue) from decline (lightpink). The chart renders the top ten states by population change, with bars extending from a central zero axis. Built with d3.js, it employs `d3.scaleLinear` for the numeric axis, `d3.scaleBand` for categorical states, and `d3.legendColor` for the legend, while an axis is drawn using `d3.axisBottom` and `d3.axisLeft`.

d3 bar diverging

This example shows a diverging bar chart of United States rural population growth from 2000 to 2009, using a diverging color scale from ColorBrewer to distinguish positive and negative growth values. The visualization loads CSV data from a GitHub gist, which is based on the Corgis global development dataset, and renders it as SVG bars using D3 v7. The chart uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the categorical year on the y-axis, and a `d3.scaleDiverging` with the RdBu color scheme for encoding value magnitude. The d3-legend library adds a sequential color legend, while axis labels and ticks are generated with standard D3 axis methods.

A6 Qualitative Scatter Plot

This scatter plot displays the relationship between burglary and motor crime rates across U.S. states from 2015 to 2019, with each dot representing a state-year observation. The visualization uses color to distinguish years, employing an ordinal color scale with a d3.legendColor legend. Hovering over a dot reveals precise values through SVG title tooltips. The chart is rendered with D3 v7, using d3.scaleLinear for both axes and d3.scaleOrdinal for color mapping, with data sourced from the CORGIS dataset.
