This example visualizes monthly global land-surface temperature anomalies from 1753 to 2015, using a heatmap of red rectangles over an SVG. It relies on React and D3 v7 (via `json`, `scaleLinear`, and `scaleBand`) to render axes, tooltips, and color opacity based on temperature variance. The data comes from the freeCodeCamp global-temperature JSON file. Hovering over a bar displays the year, month, actual temperature, and variance using a positioned tooltip.

fcc-d3-01

A heatmap visualizes monthly global land-surface temperature variations from 1753 to 2015, with the base temperature displayed as a subtitle. Each cell represents a month-year pair, colored by year and opacity scaled by temperature deviation. The visualization uses d3.json to load data from a freeCodeCamp repository, d3.scaleOrdinal, d3.scaleLinear, and d3.scaleBand for scales. SVG rendering includes custom axes, ticks, and a hover tooltip that displays the exact year, month, and temperature values.

Visualize Data with a Heat Map| fcc project-3

This heat map visualizes monthly global land-surface temperature anomalies from the freeCodeCamp ProjectReferenceData dataset, showing temperature variance across years and months. The visualization uses a color scale ranging from light blue to dark red to represent temperature deviations from the base temperature, with a legend indicating the temperature ranges. Built with React and D3 v7, the map uses `scaleLinear` for the x-axis (years), `scaleBand` for the y-axis (months), and SVG rectangles for each cell. Interactive tooltips display the exact year, month, temperature, and variance on mouse hover.

Fork of Heat Map: Monthly Global Land-Surface Temperature

This visualization displays monthly global land-surface temperature anomalies from 1753 to 2015, with each cell representing a month-year combination colored by temperature variance from a base of 8.66°C. The tooltip reveals exact temperature and variance values on hover. Built with D3 v5, it uses `scaleTime` for axes, `scaleOrdinal` for the color legend, and `d3-tip` for interactive tooltips. Data comes from the FreeCodeCamp global-temperature JSON, rendered as SVG rectangles with a custom color scale ranging from deep blue to dark red.

Heat Map

This heat map visualizes monthly temperature variances across years for a global temperature dataset. The SVG graphic uses a color-coded grid of rectangles to represent data points, with the x-axis showing year and the y-axis displaying months. Built with React and D3 v5, the code leverages `scaleLinear` and `scaleBand` for positioning, along with `axisBottom` and `axisLeft` for the chart axes. The data comes from a JSON file loaded via `d3.json`, and hover effects are implemented with CSS styling on the rectangle elements.

Fork of Heat Map: Monthly Global Land-Surface Temperature

This fork of a FreeCodeCamp project renders a heat map of monthly global land-surface temperature anomalies from 1753 to 2015, with color encoding temperature values relative to a base of 8.66°C. Each cell represents a month-year combination, and hovering reveals a tooltip with the exact temperature and variance using the d3-tip library. The visualization uses d3.v5 with SVG rendering, fetching data from a remote JSON file, and implements custom color scales, time-based axes, and a color legend within a `d3.select`-driven SVG container.

Heat Map: Monthly Global Land-Surface Temperature

This heat map visualizes monthly global land-surface temperature anomalies from 1753 to 2015, with a base temperature of 8.66°C. Each cell represents a month and year, colored by temperature variance using a custom 14-color scale. The visualization is built with D3 v5, using `scaleTime` for axes, `scaleLinear` for color mapping, and SVG rectangles for rendering. Data is fetched from the FreeCodeCamp ProjectReferenceData JSON source, while the legend and axis labels are generated with `axisBottom` and `axisLeft`. The code includes commented-out tooltip logic, but no interactive tooltips are active in the final render.

Monthly Global Land-Surface Temperature

This visualization displays monthly global land-surface temperature anomalies from 1753 to 2015, using a base temperature of 8.66°C. A heatmap grid shows each month-year combination as a colored cell, with colors ranging from deep red (cold) to dark blue (warm). The D3.js code fetches JSON data from a FreeCodeCamp repository, scales the temperature values linearly, and renders an SVG with axes for years and months. d3.scaleTime, d3.scaleLinear, d3.axisBottom, and d3.axisLeft handle the scales and axes, while a separate legend shows the color scale.

Monthly Global Land Surface Temperatures

This visualization displays monthly global land surface temperatures from 1753 to 2015, with each cell’s color representing variance from the 1951–1980 average. A hover tooltip reveals the exact month, year, and temperature anomaly. The SVG chart uses d3.scaleTime for the x-axis, d3.scaleQuantize for color mapping, and d3.json to load the FreeCodeCamp dataset. Animated transitions appear only in the tooltip’s opacity changes, while a gradient legend is built with d3.scaleLinear and linearGradient stops.
