Visualize a string/sequence, emphasizing certain substrings

Graphics[{Gray, EdgeForm[Gray], FaceForm[LightBlue], 
   SequenceReplace[Flatten[Join[{1}, {#[[1]] - 1, 
     Rectangle[{#[[1]], -5}, {#[[2]], 5}], #[[2]] + 1} & /@ 
   StringPosition[seq, Alternatives @@ segments], {StringLength @ seq}]],
 {a_Integer, b_Integer} :> Line[{{a, 0}, {b, 0}}]]}, ImageSize -> 800]

Also

Graphics[{EdgeForm[Gray], FaceForm[LightBlue], 
  Rectangle[{#[[1]], -5}, {#[[2]], 5}]& /@ StringPosition[seq, Alternatives @@ segments]},
  Axes -> {True, False}, Ticks -> None, 
  PlotRange -> {{0, StringLength @ seq}, Automatic}, ImageSize -> 800, 
  Method -> {"AxesInFront" -> False}]

Alternatively, use NumberLinePlot:

NumberLinePlot[Interval/@StringPosition[seq,  Alternatives @@ segments], 
 Spacings -> 0, Ticks -> None, ImageSize -> 600, 
 PlotStyle -> Directive[Opacity[1], PointSize[0], CapForm["Butt"], Thickness[.02]], 
 PlotRange->{{0, StringLength @ seq}, Automatic}]

seq must be a string 

Graphics[{Blue, Line[{{0, 15}, {StringLength@seq, 15}}], 
Rectangle[{#, 0}, {#2, 30}] & @@@ StringPosition[seq, segments]}]
