This example presents two SVG charts created with D3.js (v7). The top panel is a multi-series line chart rendering three synthetic variables (VarA, VarB, VarC) across 150 samples, with each series distinguished by color and a legend. The bottom panel combines a bar chart with a line overlay for the same random dataset, using a band scale for the x-axis and a linear scale for the y-axis. Both charts employ D3's axis, line, and scale APIs alongside standard SVG elements.

SVG Bar Chart

This example presents a combined bar and line chart rendered entirely as inline SVG. Five color-coded bars (A–E) represent values on a primary axis, while a connected orange line with circular markers traces a second series scaled against a parallel axis on the right. The chart uses manual SVG primitives like `<rect>`, `<path>`, and `<circle>` with explicit coordinate and height attributes, styled via the Poppins font and hover opacity transitions. Gridlines and dual-axis labels clarify the two independent value ranges.

Basic bar+line chart

This chart combines a bar chart and a line chart in a single SVG visualization, with bars representing one data series and a line overlaid for a second series. It is built as a reusable template driven by a CSV file, where column names for the x-axis, bar values, and line values are configured in the code. The x-axis uses a band scale for categorical years, while the y-axis is linear and shared by both series. Blue bars show the primary values, and a green line connects the secondary values, with a legend distinguishing the two. The chart includes axis labels, a title, and a hover effect on the bars.

SVG Bar Chart w/ Curved Line

This example presents a hybrid bar and line chart. Five labeled bars display categorical values, while two distinct line charts—one straight and one using Bezier curves—overlay the same categories to show different trend representations. The visualization uses raw SVG elements, including `rect`, `path`, and `circle`, to render the graphics. The code uses straight and curved paths, with axes, labels, and gridlines implemented via SVG line and text elements.

Bar and Line chart

This example displays a dual-axis chart combining bars for effective rainfall and a line with points for water level over time. The visualization uses two scales, time on the x-axis, and separate linear scales for the bar and line values. Panning and zooming are implemented via d3.zoom, rescaling both axes and updating the shapes. Data is loaded from two CSV files using d3.csv, and all elements are rendered as SVG.

multi charts

This example presents two SVG charts built with D3.js v7, both visualizing daily sales trends for three series (A, B, C) from `sales_trends.csv`. The top chart displays multi-series line plots, while the bottom combines bars for series A and B with an overlaid line for series C. The code uses `d3.csv` with `d3.autoType` for data loading, `d3.scaleTime` and `d3.scaleLinear` for axes, and renders interactive tooltips styled via CSS.

Bar Chart Example

This example demonstrates a basic bar chart built with D3 version 6. It visualizes a small dataset of four categorical values using an SVG container. The code creates an SVG, applies d3.scaleBand for the x-axis and d3.scaleLinear for the y-axis, then renders steelblue rectangles for each data point. It also appends axes with d3.axisBottom and d3.axisLeft.

D3: Drawing a Bar Chart

This example demonstrates a basic bar chart built with D3 v7 in an SVG container, visualizing an array of 20 numeric values. The bars grow downward from the top of a 500×100 pixel canvas, with each bar’s height proportional to its data value multiplied by 4, and its fill color transitioning from dark to lighter blue based on the data. The chart also overlays each bar with white, 11px sans-serif text labels showing the exact data values, centered horizontally within each bar. The code uses `d3.select` to append SVG elements and the data-join pattern with `.enter()` to create rectangles and text nodes.

Barplot

This example shows two bar charts side by side, both visualizing the same array of numbers. The first chart renders the bars using a standard JavaScript for loop, while the second uses D3’s data join with `selectAll`, `data`, and `enter` to create the rectangles. Both charts are drawn as SVG elements, with static positioning for x and y coordinates and bar heights proportional to the data values. The code relies on D3 v5 APIs such as `d3.select`, `append`, and attribute setters, and includes background coloring, axis lines, and titles for each chart.
