This example visualizes temperature readings over time from a CSV file as a line chart with overlaid circles marking each hourly data point. The code uses D3 v5 modules including `scaleTime`, `scaleLinear`, `line`, `axisLeft`, and `axisBottom` to render an SVG graphic. The temperature data is parsed, sorted, and scaled to fit within a 960×500 SVG canvas, with axes generated via D3’s axis components. The chart demonstrates fundamental D3 data-join and DOM manipulation techniques for creating and styling SVG elements.

Making Bar chart with D3

A bar chart displays monthly values from a CSV file, using horizontal bars where length encodes value and vertical position encodes date. The visualization is built with D3 v5, using `scaleLinear` for the value axis, `scaleBand` for the categorical date axis, and `axisLeft`/`axisBottom` for tick marks. SVG rectangles are rendered from the loaded data, with axes simplified by removing domain and tick lines.

Fork of Making a bar chart

This example visualizes temperature data from San Francisco over time, showing a smooth line chart with overlaid circular markers for each data point. The line is drawn using `d3.line` with `curveBasis` for interpolation, while `d3.scaleTime` and `d3.scaleLinear` map timestamps and temperature values to the SVG canvas. Axes are generated with `d3.axisLeft` and `d3.axisBottom`, and data is loaded asynchronously via `d3.csv` from an external dataset. The SVG rendering includes styled grid lines, axis labels, and a title.

Let's make a temperature chart bar

This bar chart displays temperature readings for six labeled controllers, ranging from 5 to 60 degrees. The data is loaded from a local CSV file and rendered as SVG rectangles with axes. Built with D3 v5, it uses `scaleBand` and `scaleLinear` for positioning, `axisBottom` and `axisLeft` for tick marks, and `csv` for data parsing. Each bar’s height corresponds to its temperature value, with the y-scale inverted to align with the SVG coordinate system.

Making a Bar Chart

A bar chart illustrates data from a CSV file, mapping values to rectangular bars. The example demonstrates fundamental DOM manipulation with D3.js v5, using `d3.select` and `d3.csv` to load data and append SVG elements. It renders the visualization into an SVG container with fixed width and height, applying styling from an external stylesheet. The chart shows how to bind data to elements and create a basic bar layout.

Making a Bar Chart

This bar chart displays hourly temperature forecasts from a weather API, with bars representing temperatures over a 40-hour period. The visualization animates bars growing from the bottom using D3 v5 transitions with a bounce ease, while hover interactions highlight bars in yellow and show tooltips with exact values. Colors transition from white through blue to red based on temperature ranges using a linear scale. The chart pulls data from a local `forecast.json` file and renders as an SVG.

Charts for Fun

Two linked charts display temperature data over time, with a bar chart and a scatter plot sharing the same dataset and axes. The bar chart uses `scaleBand` for the y-axis and `scaleLinear` for the x-axis, while the scatter plot employs `scalePoint` for discrete timestamps. Both render as SVG and customize D3 v5 axes with `axisLeft` and `axisBottom`, removing domain lines and adding axis labels. The data comes from a CSV file loaded via `csv()`, with temperature values multiplied by 1000 for display.

Making a Bar Chart

This example demonstrates how to build a horizontal bar chart from CSV data using D3 v5 with SVG rendering. It shows population values for various countries, with each bar’s length scaled linearly and categorical labels positioned along the y-axis via `d3.scaleBand`. The code loads `data.csv`, formats population numbers, and renders axes using `d3.axisLeft` and `d3.axisBottom`, alongside rectangles styled with CSS. The visualization highlights the core workflow of data loading, scaling, and SVG element creation in D3.

Making a bar Chart

This SVG bar chart displays the relationship between two variables from the file data.csv, with bar heights proportional to the data values. The visualization is built using D3 version 5, where a single SVG element of 960 by 500 pixels is selected via the d3.select method, and its dimensions are parsed with parseFloat and the unary plus operator. The data is loaded asynchronously using the d3.csv function, and the chart is rendered in an HTML page that links to the D3 library from a CDN.
