This chart shows the percentage difference in the rate of congressional incumbents from the historical average, across sessions from 1979 to 2013. Positive values are green bars above the zero line, negative values brown bars below it, revealing alternating periods of above- and below-average incumbent rates. Built with D3 v2, it uses an ordinal x-scale for year labels and a linear y-scale for the variation, with SVG rectangles rendered by a reusable `columnChart()` function. The data comes from the 'Congress rev 01' dataset.

Difference Chart

This visualization compares public approval, disapproval, and undecided ratings for multiple U.S. presidents by aligning their time in office along a common axis. It renders three separate charts side-by-side, each showing two presidential terms overlaid. The chart uses filled red and blue areas to highlight where one president’s rating exceeds the other’s, with dark red and dark blue lines tracing each individual series. The code uses D3 v3 with `d3.time.scale` and `d3.svg.area` to interpolate between sampled data points from CSV files. Data is sourced from the UCSB presidency popularity dataset.

graph2

A donut chart displays the partisan composition of the U.S. Senate across five congressional sessions, from the 112th through the 116th Congress. Users select a specific congress from a dropdown menu, which triggers animated transitions between the donut’s arc segments and updates the numeric labels positioned along thin connector lines. Built with D3 v5, the visualization uses `d3.pie`, `d3.arc`, and `transition.attrTween` to interpolate geometry smoothly, while `d3.scaleOrdinal` assigns colors to Republicans, Democrats, and Others. The underlying data is embedded as an array of objects containing seat counts per party for each session.

Data Summary

This block displays a statistical summary of a dataset on U.S. Congress members, using Datalib to compute and render summary statistics from a CSV file. The visualization presents key measures for each numeric column—such as age and term start—including counts, means, standard deviations, minimums, and maximums, alongside categorical variable breakdowns like chamber and party. The data, sourced from Five Thirty Eight, is loaded from a remote CSV and summarized in a clean tabular layout. Built with D3 v4 and Datalib, it offers a quick overview of the dataset's shape and can be adapted for other data by swapping the source file.

Women in House of Representative

This line chart visualizes the total number of women in the U.S. House of Representatives across a selected range of years, highlighting the growth in female representation. The SVG rendering uses d3.v5 with `scaleLinear`, `axisBottom`, `axisLeft`, and a `line` generator with `curveBasis` to draw the red trend line. Data is loaded via `csv()` from a GitHub gist, and the code filters to rows 44–52 before plotting, with axes labeled “Years” and “Total Number of Women.”

base scatter plot rev 02

This scatter plot animation explores the relationship between the percentage of women in Congress and the number of movie tickets sold per year from 2000 to 2013, with each point representing a year. Points are rendered as SVG circles and transition smoothly between years, drawing from two CSV datasets—one containing film records with Bechdel test results and the other with yearly demographic data. The animation highlights trends in women’s congressional representation against box-office attendance, with the points shifting over time to reveal patterns across the 14-year span.

Fork of Women in Parliament

This chart uses a green area graph with a red stroke to show the total number of women in the U.S. Congress from 1993 to 2000, based on a CSV dataset from a GitHub gist. Built with d3.v5, it uses `area`, `scaleLinear`, `axisBottom`, and `axisLeft` to render the SVG, with the x-axis labeled "Years" and the y-axis labeled "Women_total." The visualization is a fork of an original example, and it only displays a sliced subset of the data (rows 44–52).

Untitled

This interactive bar chart displays the percentage of survey respondents by racial group who overreport voter turnout in three U.S. election years (2008, 2012, 2016). Buttons trigger updates between datasets, animating bar heights via D3 transitions. The visualization uses D3 v6 with `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the y-axis, and d3-axis to render both axes. Each bar’s y-position and height are recalculated from the value property, with a 1000-millisecond transition applied to all entering, updating, and exiting rectangles.

combined chart

This combined chart displays voting data over time, using a bar chart to show Democrat votes and overlaid line charts for Republican and Independent votes. The visualization is rendered as an SVG graphic using the D3.js library, with a clean white background and labeled axes. Data is loaded from a CSV file and parsed to numeric values, then scaled using D3's band and linear scales. A legend and gridlines help distinguish the data series, while the x-axis labels are rotated for readability.
