SVG arg fadeout/gradient effect

I'm trying to create doughnut visualization using d3 with fadeout/gradient effect for each arc like this: enter image description here

I've tried to add 'filter: drop-shadow(0 0 10px color)' but it doesn't give me this effect, also, it spread on both sides.

So I moved to use two pies

  1. Outer solid color
  2. Inner with (hopefully) the fade out effect

I know in gradient I can make solid, then fade out but since I don't have a clear path to success, I split to two pies

I've tried to use both linearGradient & radialGradient on the second pie which seems like a step in a good direction, but the gradient effect changes as the arcs angles are different:

enter image description here

For the simplicity, currently I created a gradient filter for just one color as I'm not sure this is the solution for my problem...

I've added a snippet to help the helpers :)

const colors = ['red','green','purple','blue','orange','teal']
const data = [10,12,33,112,22,4];
const pie = d3.pie().padAngle(0.03);
const arcs = pie(data);

const svg = d3.select('body')
  .append('svg');
 
const svgDefs = svg.append('defs');

const mainGradient = svgDefs.append('radialGradient')
                .attr('id', 'mainGradient');

            mainGradient.append('stop')
                .attr('stop-color', 'red')
                .attr('offset', '10%');

            mainGradient.append('stop')
                .attr('stop-color', 'pink')
                .attr('offset', '90%');



d3.select('body')
  .style('position', 'relative')
  .append('svg')
  .style('position', 'absolute')
  .style('z-index', 10)
  .attr('width', 600)
  .attr('height', 600)
  .append("g")
  .attr("transform", "translate(100,100)")
  .selectAll('path')
  .data(arcs)
  .enter()
  .append('path')
  .attr('d', (a,b,c) => d3.arc()({...a, innerRadius: 96, outerRadius: 100}))
  .style('fill', (d, index) => colors[index])

 svg.style('position', 'absolute')
    .attr('width', 600)
    .attr('height', 600)
  .append("g")
    .attr("transform", "translate(100,100)")
    .selectAll('path')
    .data(arcs)
    .enter()
    .append('path')
      .transition()
      .attr('d', (a,b,c) => d3.arc()({...a, innerRadius: 0, outerRadius: 96}))
      .style('fill', 'url(#mainGradient)')

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...
