This bar chart displays average engine horsepower for seven car manufacturers, sorted from lowest to highest, with bars colored according to a sequential red color scale that maps horsepower values to increasingly darker shades. A yellow tooltip appears on mouseover, showing the exact manufacturer and horsepower value. The visualization is built with D3 v6, using `scaleBand`, `scaleLinear`, and `scaleQuantize` for positioning and color encoding, along with the ColorBrewer Reds palette and the d3-legend library. Data is loaded from a CSV file via `d3.csv`, and rendered as SVG rectangles with interactive hover effects.

Fork of Bar chart with a Sequential color scale

This bar chart displays the average horsepower for seven car manufacturers, sorted from lowest to highest, with a sequential red color scale encoding the same value. The visualization is rendered in SVG using D3 v6 and the d3-legend plugin, with a quantized color scale from colorbrewer. Hovering over a bar triggers a tooltip with the exact horsepower value. The chart includes labeled axes, a legend, and animated opacity transitions on the tooltip.

Fork of Bar chart with a Sequential color scale New

This bar chart displays the average horsepower for seven car brands, sorted in ascending order and colored with a sequential red scale that maps horsepower values to color intensity. Built with D3 v6, the visualization uses `d3.scaleBand`, `d3.scaleLinear`, and `d3.scaleQuantize` to position and color the bars, while a tooltip appears on mouseover. The rendering is SVG-based, with axes, a color legend, and animation effects, drawing data from a CSV file named `barchart.csv`.

Fork of Bar chart with a Sequential color scale

This bar chart displays the average horsepower for seven car brands, sorted from lowest to highest, with each bar colored according to a sequential red color scale that encodes the horsepower value. The visualization loads data from a CSV file using d3.csv, binds it to SVG rectangles, and uses d3.scaleBand, d3.scaleLinear, and d3.scaleQuantize for positioning and color mapping. Interactive tooltips appear on mouseover, while d3.legendColor adds a legend, and axes are rendered with d3.axisBottom and d3.axisLeft.

Fork of Bar chart with a Sequential color scale

A sequential bar chart displays average horsepower for seven automobile brands, sorted from lowest to highest, with color intensity increasing alongside value. The visualization uses D3 v6 to construct SVG rectangles scaled by `d3.scaleBand` and `d3.scaleLinear`, while a `d3.scaleQuantize` maps horsepower values to a seven-step reds palette from colorbrewer. Hovering reveals a tooltip with the exact value, and an interactive legend and axes are generated using `d3.legendColor` and axis components. Data comes from a CSV file provided in the accompanying `barchart.csv`.

Assignment 6 -- Bar chart with a Sequential color scale

A bar chart displays average engine horsepower for seven car makes, sorted from lowest to highest, with a sequential red color scale encoding the horsepower value. The chart uses D3 v6 with SVG rendering, including axes, a color legend, and a tooltip that shows the exact value on hover. The code reads data from a CSV file, applies a quantized color scale from the ColorBrewer library, and uses the d3-legend API to generate the legend.

Fork of Bar chart with a Sequential color scale

This bar chart displays the average horsepower of car makes, sorted from lowest to highest, with a sequential color scale from light to dark red indicating increasing values. It uses D3 v6 with SVG rendering and includes interactive tooltips on hover, as well as axis labels and a legend. The code employs `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.scaleQuantize` with `colorbrewer.Reds[7]` for the color mapping. Data is loaded from a CSV file and filtered to seven specific makes.

This bar chart displays the average engine horsepower for seven car brands, sorted in ascending order and colored with a sequential red color scale. Built with D3 v6 and rendered as SVG, the visualization uses d3.csv to load data, d3.scaleBand and d3.scaleLinear for axes, and d3.legendColor to add a legend. A hover tooltip shows precise values, while the code references data from a local barchart.csv file.

Fork of Fork of Bar chart with a Sequential color scale

A horizontal bar chart displays the average horsepower of seven car brands, from Volkswagen to Mercedes-AMG, sorted in ascending order. Bars use a sequential color scale from the ColorBrewer Reds palette, rendered as SVGs via D3 v6, with a hover tooltip showing exact values. The code loads data from a CSV, applies `d3.scaleBand`, `d3.scaleLinear`, and `d3.scaleQuantize`, and uses the d3-legend library to generate a color legend.
