show word and year instead of date and value

Dec 27 2022 6:19 AM

I am using Barchart to show dummy data but instead of date and value, i want word and year 

for example: word{Paddy,Maize,Wheat,Pulses,Oilseed,Fodder,Vegetables}

year{2001,2002,2003,2004,2005}

import * as Plot from '@observablehq/plot';
import * as d3 from 'd3';

import * as PieChart from './piechart';

var spos =
