This visualization plots Portland public schools by their OverallRating, using position and color to compare current and previous performance metrics. Each school is represented as a point, with the x-axis showing current math proficiency percentages and the y-axis showing attendance percentages; point size encodes the number of students, while color indicates the school type (Elementary, Middle, High School). The chart also distinguishes rating categories—Outstanding, Satisfactory, or In Need of Improvement—via glyph shape, and includes previous-year math and attendance values as faded reference points, making it easy to see improvement or decline across schools.

Portland Schools: Math Standards

A horizontal bar chart ranks Portland Public Schools by the percentage of students meeting or exceeding math standards in the previous year. The data is loaded from a CSV file using d3.csv, sorted descending by MathPctPrev, and visualized as an SVG with ordinal y-axis for school names and linear x-axis for percentages. Hovering over each bar shows the school name and its percentage. The chart includes axes on both top and bottom, with bars colored in a reddish tone.

Portland Schools: Math Standards

This example displays the percentage of students meeting or exceeding math standards from the previous year for Portland Public Schools. The data, loaded from a CSV file, is sorted in descending order of math performance, and each school is rendered as a horizontal bar using SVG rectangles whose widths are proportional to the percentage value. Hovering over a bar reveals the school name and its percentage in a tooltip. The visualization uses D3 v3 to bind the data and position the bars in a vertically stacked layout, with the y-axis representing the rank order of schools and the x-axis encoding the percentage.

Portland Schools: Math Standards

The scatterplot displays the percentage of students meeting or exceeding math standards in Portland Public Schools for 2011 versus 2012, with each circle representing a school. The x-axis shows the 2011 math percentage and the y-axis the 2012 percentage, with tooltips revealing the school name and both percentages on hover. Data comes from CivicApps for Greater Portland. The visualization is built with D3 v3, uses SVG rendering, and includes labeled axes with percentage ticks.

english-exams

The visualization contrasts exam grade predictions for state and private school students, showing how incorporating school type introduces systematic bias against state students. A scatterplot plots classroom scores against exam scores, overlaying trend lines for each school type, while side-by-side histograms display model prediction errors with and without the school-type adjustment. The code uses D3.js with SVG for the scatterplot and histograms, plus seeded random number generation via `seedrandom` to create synthetic student data. Simulated data points are colored orange and steelblue to distinguish school types, with tooltips attached via a custom `attachTooltip` helper.

Per-Pupil Spending vs Academic Results

This visualization shows the relationship between per-pupil spending and high school graduation rates across Massachusetts schools. It uses a binned heatmap to display the density of schools within specific spending and performance ranges, where darker blue colors indicate a higher concentration of schools. The chart is built with D3.js (v7), using `d3.csv` to load data, `d3.scaleLinear` for axes, `d3.scaleSequential` with `interpolateBlues` for the color scale, and custom binning logic to aggregate data points into rectangles. Tooltips display the exact counts and ranges on hover. Data comes from the MA_Schools.csv file.

Per-Pupil Spending vs Academic Results2

This heatmap visualizes the relationship between per-pupil spending and graduation rates across Massachusetts schools, using data from the MA_Schools.csv dataset. It shows patterns of density through color intensity, with orange-to-red hues indicating higher concentrations of schools at specific spending and performance combinations. The visualization uses D3 v7 to bin data points into a 20×15 grid, then renders SVG rectangles colored via a sequential scale (d3.scaleSequential with interpolateOrRd). Interactive tooltips appear on mouseover, while axes display spending in dollars and graduation rates in percentages, with a legend implied by the color gradient.

Massachusetts Public School Data Analysis Project

This scatter plot shows the relationship between average class size and college attendance rates for Massachusetts public schools, with each point colored by the percentage of economically disadvantaged students at that school. The visualization uses D3.js v7 with an SVG rendering approach, employing `d3.scaleLinear` for both axes, `d3.scaleSequential` with the Plasma interpolator for the color scale, and `d3.axisBottom`/`d3.axisLeft` for the chart axes. Data is loaded from a CSV file using `d3.csv`, with a tooltip providing detailed information for each school on hover.

NYC High Schools

This visualization compares NYC high school graduation rates against attendance rates using a scatterplot, and it also includes a bar chart showing the number of students per school. The scatterplot uses `d3.scaleLinear` for both axes, with `d3.axisBottom` and `d3.axisLeft` for tick marks, and circles jittered slightly to reduce overplotting. Hovering over a circle highlights all schools in the same neighborhood. The bar chart uses `d3.scaleBand` for its y-axis and `d3.scaleLinear` for the x-axis. Data is loaded as CSV from NYC Open Data, and the visualization is rendered as SVG with D3 v7.
