This line chart tracks Rhode Island’s monthly unemployment rate from 1976 onward, using data from FRED. It plots the rate over time with a steel-blue line, while red dots flag five notable spikes, including the 2020 peak. The visualization is built with D3.js and React, using `scaleTime` and `scaleLinear` for axes and a custom binary search for hover tracking. A tooltip showing exact values appears on mouseover, and grid lines and axis labels support reading the trend.

Unemployment Rate Visualization

This project visualizes the unemployment rate in Rhode Island over time using D3.js and React.

Features

Interactive line chart showing unemployment trends
Red dots marking significant spikes in unemployment:
- Spike before 1980
- Spike between 1980 and 1985
- Spike between 1990 and 1995
- Spike around 2010
- Major spike in 2020

Data Source

The data is sourced from Federal Reserve Economic Data (FRED) and represents monthly unemployment rates in Rhode Island.

Prototype v3

A line chart visualizes Rhode Island's unemployment rate from 1976 to 2020, revealing cyclical spikes marked by red dots during economic downturns. Hovering over the chart displays a tooltip with the precise date and rate at the nearest data point. The visualization uses React with D3 v7, employing `d3.csv` for data loading, `d3.scaleTime`/`d3.scaleLinear` for axes, and custom bisection logic for interactivity.

Prototype v4

This visualization shows Rhode Island's monthly unemployment rate (RIUR) from 1976 onward, highlighting historical spikes with red dots overlaid on a steelblue line chart. The React app loads data from a CSV file using d3.csv, parses dates with d3.timeParse, and renders the chart through d3.scaleTime, d3.scaleLinear, d3.line, d3.axisBottom, d3.axisLeft, and d3.extent functions. A legend distinguishes the line series from annotated spike points.

Prototype v1

This visualization displays Rhode Island’s monthly unemployment rate from 1976 onward, revealing cyclical peaks and troughs over time. Built with React and D3 v7, the app loads a CSV file, parses dates, and renders a line chart using scales, axes, and a line generator. Grid lines and labeled axes clarify the trend, with the data sourced from a local data.csv file.

Prototype v5

This visualization compares monthly unemployment rates in Rhode Island (RIUR) and the United States (USUIR) from 1976 onward using two overlaid line charts. Steel-blue and orange paths represent the respective rates, while red dots mark notable Rhode Island spikes. The chart uses d3.scaleTime, d3.scaleLinear, and d3.line to construct the axes and paths, with d3.csv loading the two datasets. React manages the component state, and the visualization renders inside an SVG with grid lines, axis labels, and a legend showing series colors and spike markers.

Prototype v6

This visualization compares Rhode Island and U.S. unemployment rates as two line charts over time, using steelblue for Rhode Island and orange for the national rate. Red circles mark notable spikes in Rhode Island data, with a legend and grid lines aiding interpretation. The React app loads CSV data with d3.csv, parses dates with timeParse, and renders the SVG using d3.scaleTime, d3.scaleLinear, d3.line, and d3.axisBottom/axisLeft. A shared y-axis domain from both datasets ensures direct visual comparison.

Fork of Basic Scatter Plot of Rhode Island Unemployment Rate using React and D3

This scatterplot displays Rhode Island's monthly unemployment rate from 1976 onward, using data from the FRED series RIUR. Points are plotted on a time-based x-axis and a linear y-axis, with steelblue circles and a tooltip showing the exact date and rate on hover. The visualization is built with React and D3 v7, using `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to render the axes, grid, and interactive elements.

Final Project - Line Chart

This line chart compares monthly unemployment rates in Rhode Island against the national US average from 1976 onward. Two colored lines, steel blue for Rhode Island and orange for the US, trace the trends across time, with red circles highlighting notable rate spikes. Built with React and D3 v7, the visualization uses `d3.csv`, `scaleTime`, `scaleLinear`, and `d3.line` to load and render data from two CSV files. A legend and axis labels clarify the comparison.

RIUR Scatterplot Iteration

This line chart shows the monthly Rhode Island unemployment rate from 1976 onward, tracking its fluctuations over time as a percentage. The visualization loads CSV data, parses dates with `d3.timeParse`, and uses `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.line` within React to render axes, grid lines, and a steelblue path. The chart includes a title and axis labels for clarity.
