This example presents a bar chart showing the number of women in select STEM majors, with each bar colored using a sequential green color scale that encodes the value. The visualization is rendered as an SVG using D3 v7, with a React-based project structure. It loads data from a CSV file, uses `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.scaleSequential` with `d3.interpolateGreens` for coloring. A legend is added via the d3-legend library to explain the color mapping.

Assignment 4: Bar Chart

This example shows the number of women in five selected STEM majors in a bar chart, with the count of females on the y-axis and the major names on the x-axis. The data is loaded from a CSV file derived from the Corgis graduates dataset. The chart is rendered as an SVG using D3 v7, with `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.axisBottom` and `d3.axisLeft` to draw the axes.

A6_BarChart with Sequential Scale

This example visualizes the happiness scores of various countries using a bar chart where each bar’s color encodes its score through a sequential blue scale. The chart is rendered as an SVG in a React application, leveraging D3 v7 for scaling and axis generation, while the color mapping is handled by `d3.scaleSequential` with the `interpolateBlues` interpolator. The data is loaded via `d3.csv` from a GitHub-hosted dataset, and a legend is added using the `d3-legend` library to clarify the score-to-color mapping. The visualization highlights the relative happiness rankings across countries while making score differences visually intuitive through color intensity.

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.

D3 - Sequential scale bar chart

This example visualizes life expectancy across different countries using a bar chart where bar colors are mapped through D3’s `scaleSequential` with an `interpolateRgb` gradient from lightgreen to darkgreen. The chart loads CSV data via `d3.csv` from a GitHub gist, renders SVG bars with `d3.axisBottom` and `d3.axisLeft` for axes, and includes a sequential color legend generated by the `d3-legend` plugin. The code explicitly sets the color scale’s domain slightly beyond the data range and applies it to each bar’s fill, while the chart’s background, title, and axis labels are all configured inline.

colored bar chart

A colored bar chart displays a dataset of numeric values as vertical bars, with color mapping from green through orange to red via a `d3.scaleLinear` domain of 0 to 110. React state management allows the user to increment, filter (values ≤ 50), or randomly append data through buttons, triggering `useEffect` updates. The SVG is rendered using `scaleBand` for x-positioning, `scaleLinear` for y-scaling, and D3 v5 axes. Bars animate on transitions, and mouseenter events create tooltips with D3 text elements that fade in.

A6 - Color Scales in D3

This example demonstrates four distinct D3.js visualizations, each employing a different color scale type: a bar chart using a sequential color scale, a diverging bar chart with a diverging scale, a scatterplot with a qualitative scale, and a line chart. The code uses D3’s `scaleSequential`, `scaleDiverging`, and `scaleOrdinal` APIs to map data values to colors. Each chart is rendered using SVG elements created via D3’s `select` and `append` methods. The visualizations are embedded as standalone pages, with the bar chart and diverging chart showing categorical comparisons, while the scatterplot and line chart reveal patterns across continuous variables.

A6 - Sequential Color Scale Bar Chart

This example visualizes average temperatures across cities using a horizontal bar chart with a sequential blue color scale. It shows how temperature values map to color intensity, with a legend on the right providing the quantitative scale. The visualization uses D3.js v6 with d3.scaleSequential and d3.interpolateBlues for the color encoding, along with d3.scaleLinear and d3.scaleBand for the axes. A linear gradient legend displays the temperature-to-color mapping, and the data comes from a CSV file hosted on GitHub Gist. The chart includes axis labels and a title, with the bars' color intensity reflecting the average temperature for each city.

Bar Chart

This example shows a bar chart with six labeled bars (a–f) of varying heights, rendered as an SVG in a React environment using D3 v3. The code defines a band scale for the horizontal axis, a linear scale for the vertical axis, and draws axes with tick marks. It uses D3’s selection and data-join pattern (`selectAll`, `data`, `enter`) to create a `rect` for each data point, with bars filled in steel blue. The data is hardcoded in the script, with margins and padding configured around the 500-by-500 pixel canvas.
