This scatter plot matrix compares weekly U.S. gasoline prices across four fuel grades—All Grades, Regular, Midgrade, and Diesel—from early 1995 onward. Each cell displays a scatter of points, with tooltips revealing the specific week and price values on hover. Built with D3 v7, the visualization uses `d3.csv` to load the data, `d3.scaleLinear` for axes, and `d3.axisBottom`/`d3.axisLeft` for tick marks. The SVG-based rendering includes a cross-product helper to generate all pairwise combinations of the selected columns.

project-SDV

This heatmap visualizes weekly U.S. retail gasoline and diesel prices from 1995 to 2021, with columns representing different fuel grades and formulations, and rows representing weekly dates. Color intensity encodes price levels, using a viridis color scale. Built with D3.js v7, the visualization renders as an SVG using `d3.scaleBand` for axes, `d3.timeFormat` for date parsing, and `d3.interpolateViridis` for color mapping. A tooltip, triggered by mouseover events, displays the column description, date, and value, while a gradient legend shows the color-to-price correspondence.

project-SDV 4

This stacked area chart visualizes the average prices of U.S. gasoline, broken down into overall, regular, and midgrade averages, across a weekly timeline. The chart uses a total height to represent the sum of these three averages for each date. Built with D3.js v7, the code computes the averages from the raw data, stacks them using `d3.stack()`, and renders the areas with `d3.area()`. An interactive legend allows users to isolate individual averages by dimming the others, and a tooltip displays precise values via a nearest-date bisector. The data is sourced from the provided CSV file.

project-SDV 5

A multi-line chart displays retail gasoline prices for four US regions (A1, R1, M1, D1) as weekly time-series data from the provided CSV. Four colored lines show price trends, each represented with a legend button. Clicking a legend button highlights the selected region’s line while dimming others; clicking again restores all. The chart uses D3 v7 with `scaleTime`, `scaleLinear`, `line`, and `curveMonotoneX`, while rendering via SVG. Points include an HTML tooltip showing exact values and dates. The visualization is built with `d3.csv`, axes via `axisBottom` and `axisLeft`, and interactive filtering through `selection.on` and `selection.attr`.

project-SDV 3

This parallel coordinates chart visualizes 13 numeric petroleum price attributes across weekly dates from a CSV file, with each line representing a time series. The D3 v7 code renders SVG paths for all data points in blue, with axes scaled linearly per dimension. Interactive legend buttons allow filtering by dimension, highlighting lines in the top 10% of values for the selected attribute while dimming others. Tooltips display the week date on hover, and the line generator uses `d3.line()` with `d3.scalePoint()` for positioning.

GasPrice

The visualization displays diesel fuel prices from multiple gas stations over one week, using a single line chart with a time-scaled x-axis and a linear price y-axis. The SVG rendering uses D3 v7 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and a `line` generator with `curveBasis` smoothing. Data is loaded via `d3.csv`, with dates parsed and prices converted to numbers, and the chart includes gridlines and labeled axes.

sketch with D3

This scatter plot visualizes the relationship between car price and mileage, with each circle representing a vehicle and its color indicating fuel type (Petrol, Diesel, Hybrid, or Electric). Using D3 v7, the code loads data from an external CSV file, converts numeric fields, and renders an SVG with linear scales for both axes. The visualization includes labeled axes, a title, and a custom legend built from the distinct fuel types. d3.csv fetches the data, while d3.scaleLinear and d3.scaleOrdinal handle the positional encoding and categorical color mapping respectively, with d3.axisBottom and d3.axisLeft generating the tick marks.

Scatter Plot

This scatter plot visualizes a car dataset, showing fuel efficiency versus price with points colored by car type. Built as a reusable D3.js chart function, it uses `d3.scaleLinear` for both axes, `d3.scaleOrdinal` with `d3.schemeSet2` for categorical colors, and SVG circles with hover tooltips. The data is loaded from a CSV file via `d3.csv` with `d3.autoType`, and rendered in an SVG container with axes generated using `d3.axisLeft` and `d3.axisBottom`.

Scatter plot

This interactive scatter plot displays the relationship between car mileage and price, with individual dots colored by fuel type. Built with D3.js (v7), it renders as an SVG chart with axes, labels, and a hover tooltip that reveals the car name, fuel, mileage, and price. The visualization loads a CSV dataset from a GitHub gist, uses `d3.scaleOrdinal` for color mapping, and applies CSS transitions to highlight dots on hover.
