But when i am copy pasting this code to say "temp.jsp" page its not rendering and chart is not coming.
need suggestions

I see in your title you mention flexigrid :) You should update it.
To answer your question, there are 2 possible issues:
1. Make sure that "data/json.json" is served OK (not a 404 error)
2. Having the file as .jsp might mean you need extra code for it.

How to plot x axis values over bars?

I changed the attributes of the X axis to plot its values over the bars of the chart. But anywhere I put the code, the values are always plotted before ("behind") the bars and therefore we cannot see it.
//This part of the code is OUTSIDE of the update function (line 44 of the fiddle)
//append group to plot X axis
const xAxisGroup = g.append("g")
.attr("class", "x axis")
.attr("transform", `translate(0, ${HEIGHT})`)
//This part of the code is INSIDE the update function (line 92)
const xAxisCall = d3.axisBottom(x)
xAxisGroup.call(xAxisCall)
.selectAll("text")
.attr("x", "-5") // <<<--- I change this to 50
.attr("y", "10")
.attr("text-anchor", "end")
.attr("transform", "rotate(-45)") // <<<--- I changed this to -90
How would be possible to plot this values over the bars instead?
This is the fiddle of the original chart and this is the modified one. The month values may be behind the bars... :-/
In an SVG, whatever is painted later stays on top. So, just append your x axis <g> element after painting the rectangles. Alternatively, raise it:
xAxisGroup.raise()
Here's your code with that change:
//set general margin, width and height values
const MARGIN = {
LEFT: 128,
RIGHT: 8,
TOP: 32,
BOTTOM: 128
}
const WIDTH = 400 - MARGIN.LEFT - MARGIN.RIGHT
const HEIGHT = 300 - MARGIN.TOP - MARGIN.BOTTOM
//append svg plot area into div chart area
const svg = d3.select("#chart-area").append("svg")
.attr("width", WIDTH + MARGIN.LEFT + MARGIN.RIGHT)
.attr("height", HEIGHT + MARGIN.TOP + MARGIN.BOTTOM)
//append group into svg
const g = svg.append("g")
.attr("transform", `translate(${MARGIN.LEFT}, ${MARGIN.TOP})`)
//X label
g.append("text")
.attr("class", "x axis-label")
.attr("x", WIDTH / 2)
.attr("y", HEIGHT + 60)
.attr("font-size", "20px")
.attr("text-anchor", "middle")
.text("Month")
//Y label
g.append("text")
.attr("class", "y axis-label")
.attr("x", -(HEIGHT / 2))
.attr("y", -60)
.attr("font-size", "20px")
.attr("text-anchor", "middle")
.attr("transform", "rotate(-90)")
.text("Value")
//set scale for X axis
const x = d3.scaleBand()
.range([0, WIDTH])
.paddingInner(0.3)
.paddingOuter(0.2)
//set scale for Y axis
const y = d3.scaleLinear()
.range([HEIGHT, 0])
//append group to plot X axis
const xAxisGroup = g.append("g")
.attr("class", "x axis")
.attr("transform", `translate(0, ${HEIGHT})`)
//append group to plot Y axis
const yAxisGroup = g.append("g")
.attr("class", "y axis")
//import data
d3.csv("https://raw.githubusercontent.com/dbahiense/sotabook/main/revenues.csv").then(data => {
//parse values
data.forEach(d => {
d.revenue = Number(d.revenue)
d.profit = Number(d.profit)
})
//listen drop-down lists and trigger update function on change
//state

})
//set domains for X and Y axes
x.domain(filteredData.map(d => d.month))
y.domain([0, d3.max(filteredData, d => d.revenue)])
const xAxisCall = d3.axisBottom(x)
const yAxisCall = d3.axisLeft(y)
//.tickFormat(d => d + "m")
yAxisGroup.call(yAxisCall)
// JOIN new data with old elements.
const rects = g.selectAll("rect")
.data(filteredData)

D3.js axis label overlapping axis scale

I have the following example:
Please note that this code is just a combination of code I have found online.
Is there a way to prevent the Axis label/title from overlapping the axis scale/numbers? For example here the label is overlapping the numbers. In this example I could manually hardcode the label to be positioned more to the left which would work. However, what happens when we use changing data?
Say the data in the graph changes such that the y axis number may be in the 10s in one example but the next data set may have values in the 1,000,000's. Is it possible to make the graph/axis titles more dynamic/responsive to changing number lengths?
Is this something that can be done in the chart setup or is this as css issue. All suggestions or solutions are welcome.
I do not have much experience with D3.js so this may be a very simple issue to fix, I hope someone can help.
Thank you

I can't load a javascript scatter plot in any browser

Recently, maybe after updating Java, I'm unable to load a scatter plot on Chrome, Firefox or Internet Explorer.
One month ago, everything loaded fine. I don't know what happened. I've updated Java to the last version and enabled ActiveX on Internet options, but nothing works for me.
I'll paste the html code. It loads the point info using a csv file saved in the same folder:

It looks like main issue is code is not formatted properly.
Many comments get mixed with the code caused the syntax errors.
I try to format the code and try to fix those errors.
As we don't have your data.csv file so we are not able to load that data but code creates the chart now.
You can try to use this code on your side with your data.csv file. It will help you to load the chart properly.

Graphing Uploaded data in d3

I am trying to use uploaded csv file data to be graphed using a d3. However I keep getting the error message that d3 isn't defined. Here's a sample of the code. The csv file is consists of 3 columns and 300 rows, separted by commas.

I guess this could be fixed for now by adding a timeout for all your js code, as your d3 lib is loaded from cdn which may take few seconds.

But when i am copy pasting this code to say "temp.jsp" page its not rendering and chart is not coming.I am running this page on tomcat server.
need suggestions
It is not because you saved it as jsp or html page. You need to add charset="UTF-8" to your script declaration as d3.js uses UTF characters.
eg.
<script src="http://d3js.org/d3.v3.js" charset="UTF-8"></script>
