plot data_file using 1:2 with box fs solid title ""

I am using the above command to plot a bar graph in gnuplot. But the graph generated is a sort of continuous step graph where the width of each box is very high.

data.csv is

"MCU", 1.8
"Radio Tx", 19.5
"Radio Rx", 21.8
"Flash READ", 4
"Flash WRITE", 20

While the content of script should be ( gnuplot.script)

set boxwidth 1 relative
set style data histograms
set style fill solid 1.0 border -1
set datafile separator "," 
plot 'data.csv' using 2:xticlabels(1) notitle

set terminal png truecolor font small size 600,500
set output 'image1.png'
replot

$ gnuplot gnuplot.script
