Customizing Axes

This example presents a horizontal bar chart of opera type counts from a CSV file, demonstrating custom D3 axis styling. The y-axis removes domain and tick lines for a cleaner look, while the x-axis applies a custom tick formatter using `d3.format` to abbreviate large numbers and replaces "G" with "B". The code uses `d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`, with SVG rendering and CSS controlling tick, label, and title appearance.

Cars Scatter Plot

This scatter plot visualizes movie scores against their counts, with each red circle representing a data point from a local CSV file. The x-axis encodes the count value while the y-axis shows the score, using linear scales. The visualization is rendered as an SVG with D3 v5, leveraging `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` to construct the axes and plot. Axis labels and a title are added as SVG text elements, with styling applied via external CSS for tick marks and circle opacity.

Cars Scatter Plot

This example visualizes the relationship between horsepower and weight for a dataset of cars, with each car represented as a semi-transparent red circle. The scatter plot uses D3.js version 5, leveraging scales such as `scaleLinear`, axes generated with `axisBottom` and `axisLeft`, and data loaded via `csv` from a remote dataset. The SVG rendering includes styled axis ticks, grid lines, and labeled axes, with circle positions mapped through `xScale` and `yScale` based on the data’s extent.

Scatter Plot

This scatter plot shows the population counts of the top 10 most populous countries, with each country positioned along a categorical y-axis and a linear x-axis scaled to population values. The visualization uses D3 v5 APIs including `scaleLinear`, `scalePoint`, `axisLeft`, `axisBottom`, and `format` to render the SVG output. Data is loaded from a CSV file and processed by multiplying the population figures, with circle marks and axis labels styled via CSS.

Bar Chart

This bar chart displays the top 10 most populated countries, with population values loaded from a CSV file and converted to thousands. Using D3 v5, the visualization employs `scaleLinear` for the x-axis and `scaleBand` for categorical country labels on the y-axis, rendering bars as SVG rectangles. Axes are generated via `axisLeft` and `axisBottom`, with tick labels formatted using `format('.3s')` to abbreviate large numbers. The chart includes axis titles and a heading, styled through CSS selectors applied to SVG text elements.

Let's do a barchart with D3.js

A bar chart displays population figures for ten countries, with horizontal bars scaled by population and labeled by country. The visualization uses D3 v5 to load CSV data, convert population values, and render SVG rectangles via scales and axes. It employs `scaleLinear` and `scaleBand` for positioning, and `axisLeft` and `axisBottom` for labels, with a steelblue fill style.

Let's make a face with D3.js

A yellow circle face with black-outlined eyes and eyebrows is drawn using D3.js v5, with the facial features positioned via SVG transforms. The code builds the face programmatically using `d3.select` and `d3.arc` for the mouth, then animates the eyebrows with chained `transition.attr` calls over two seconds each, moving them downward and back upward. The rendering uses SVG elements inside a centered `<g>` group, with dimensions taken directly from the SVG attributes. The example demonstrates basic SVG construction and animation sequencing without external data.

Shapes with SVG and CSS

This example demonstrates how to assemble basic geometric shapes—circles, rectangles, lines, and paths—directly in SVG, with styling controlled through CSS and inline attributes. The SVG is scaled and grouped with transforms, while a CSS class applies stroke properties to line elements. The code uses raw SVG markup and CSS rules, with no additional libraries, showing how SVG primitives and cascading styles combine to create a static vector composition.
