d3NoobV5 Reusable Examples - Bar Chart

Simple bar graph in v5

This example shows a simple bar chart of sales figures by salesperson, with steel-blue bars and labeled axes on both sides. The data comes from a CSV file containing names and numeric sales values. The code creates a band scale for the x-axis and a linear scale for the y-axis, then uses `d3.csv` to load the data and `d3.axisBottom` and `d3.axisLeft` to render the axes. Bars are appended as SVG `rect` elements, with widths and heights computed from the scales. The chart uses D3 v5 and is rendered entirely in SVG.

Simple bar graph in v4

This example shows a simple bar chart of sales figures per salesperson, rendered as SVG rectangles. It uses D3 v4 with a `d3.scaleBand` for the x-axis and a `d3.scaleLinear` for the y-axis, pulling data from an external CSV file. The chart includes bottom and left axes via `d3.axisBottom` and `d3.axisLeft`. Data is loaded asynchronously with `d3.csv`, and bar heights are calculated relative to the maximum sales value.

Simple bar graph in v6

This example shows a simple bar graph of sales figures per salesperson, rendered as an SVG using d3.js v6. It loads data from a CSV file with `d3.csv`, maps the data to a `d3.scaleBand` for the x-axis and a `d3.scaleLinear` for the y-axis, and draws rectangles for each bar. Axes are added with `d3.axisBottom` and `d3.axisLeft`. The chart uses a fixed margin layout and steel-blue bars.

V5 Reusable Examples - Nested data, Chart series - Example 3.1

A nested bar chart displays monthly sales totals for three fruit categories, with each month’s sales aggregated and grouped by fruit type. The visualization uses a single x-axis for months and y-axis for sales values, rendering red-bordered bars per category. Built with D3 v5, it applies a reusable chart pattern based on Mike Bostock’s principles and Marcos Iglesias’ ProD3 structure. The code uses `d3.scaleBand` for x positioning, `d3.scaleLinear` for y scaling, and `d3.axisBottom`/`d3.axisLeft` for axes, with data loaded from a CSV file containing Month, Sales, and Fruit columns.

d3NoobV5 Reusable Examples - MultiLine Chart with different axes

This example demonstrates a multi-line chart with two distinct y-axes, plotting both the close and open values from a CSV dataset over time. It uses D3 v5 to render SVG elements, with a time-scaled x-axis and separate linear scales for the left and right axes, each styled with different text colors. The chart follows a reusable module pattern inspired by Mike Bostock’s “Towards Reusable Charts” and the Pro D3 book, creating maintainable, modular visualizations. The code builds scales, axes, and lines programmatically, positioning the right axis and its corresponding line alongside the left one.

d3Edge_v5ProReusable_BarChart-Ch4.1

This example demonstrates a reusable bar chart built with D3.js v5, following the Pro D3.js pattern for modular chart creation. The SVG-based visualization renders two separate bar charts from hardcoded arrays of numeric string values, with steel-blue bars and no axes. The chart employs a dispatcher object to broadcast a customHover event, which prints data values and indices to the console when the mouse hovers over a bar. The implementation uses D3’s `scaleBand` and `scaleLinear` for positioning and scaling, while the reusable `barChart` module exposes configurable width and height accessors.

d3NoobV5 Reusable Examples - MultiLine Chart

A reusable multi-line chart renders two time-series lines from a CSV dataset, plotting date against closing and opening values. The visualization demonstrates a modular chart architecture using D3 v5's SVG rendering, with scales, axes, and gridlines constructed via `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` within a pattern inspired by Mike Bostock's reusable charts. The chart draws two distinct lines from the same data columns, showing how additional series can be added to the reusable component.

d3NoobV5 Reusable Examples - MultiLine Chart (adjusted) with lines labelled

This example shows a multi-line chart with two labeled lines, plotting date against two numeric values from a CSV dataset. The chart uses D3.js v5 to render SVG elements, with scales mapping time and linear values. A reusable chart module builds axes, gridlines, and lines via `d3.axisBottom`, `d3.axisLeft`, and `d3.scaleTime`, while `data.columns.slice(1).map` transforms the raw CSV data for plotting. The visualization highlights two series, with labels drawn after the lines, and a title and axis labels included.
