Bar Chart
This bar chart displays the frequency of each letter in the English alphabet, using steelblue bars that turn brown on hover. The chart is rendered with SVG and loads its data from a TSV file containing letter-frequency pairs. It uses D3’s ordinal scale for the x-axis (letters) and a linear scale for the y-axis (frequencies, formatted as percentages), with axes generated via `d3.svg.axis`. The code leverages `d3.tsv` for data parsing, `d3.max` to set the domain, and D3’s selection and data-join methods to draw the rectangles. Margins follow the conventional layout, with the y-axis labeled "Frequency".
AI-generated descriptionThis simple bar chart is constructed from a TSV file storing the frequency of letters in the English language. The chart employs conventional margins and a number of D3 features:
- d3.tsv - load and parse data
- d3.format - format percentages
- d3.scale.ordinal - x-position encoding
- d3.scale.linear - y-position encoding
- d3.max - compute domains
- d3.svg.axis - display axes
